Motorcycle gear backpacks have one hard job: carry your helmet, gear, and daily essentials without shifting at speed, soaking through in rain, or wrecking your back on the ride home. After comparing 14 of the most popular options, the KEMIMOTO 37L Large Capacity Backpack stands out as the best overall pick thanks to its rare combination of genuine waterproofing, a full-face helmet compartment, and a built-in rain cover. Riders who haul more should look at the Oumurs 50L Expandable Helmet Bag, while commuters on a budget get strong value from the KEMIMOTO Hardshell 22L. The main tradeoff in this category is straightforward: bigger capacity means more wind drag and bulk, while sleeker hardshell designs sacrifice storage.

Key Takeaways
- KEMIMOTO dominates this roundup with five entries, but they are not interchangeable — the 37L rain-cover model wins on overall balance, while the 22L hardshell is the only true commuter-first design with carbon-fiber rigidity and a laptop sleeve.
- Capacity claims are wildly optimistic across the category: several ‘45L‘ and ’50L’ packs only reach those numbers fully expanded, so commuters should judge them at their collapsed size instead.
- Reflective detailing proved the biggest differentiator for city riders — the Riderbag Hi Viz models offer far more 360-degree visibility than packs with a few token strips, at the cost of a utilitarian look.
- True waterproofing is rare. Most bags rely on 1680D Oxford fabric, which is water-resistant at best; only packs shipping with a dedicated rain cover survived all-weather commuting expectations.
- Hardshell and softshell designs split the lineup cleanly: hardshell protects electronics and slices wind at speed, while softshell expandable models like the KEMIMOTO 20L and 35L hidden-net versions win on flexibility for stashing a helmet externally.

More Details on Our Top Picks
KEMIMOTO Motorcycle Helmet Backpack, 37L Large Capacity with USB Charging Port and Rain Cover
This option stands out for balancing capacity, weather protection, and rider comfort better than anything else in this lineup. The 37L volume swallows a full-face helmet plus a change of clothes, and the included rain cover gives it a genuine edge over the Riderbag Hi Viz Commuter, which is only weather-resistant. The USB charging port is the differentiator for commuters who run navigation or music all day, though it needs an external power bank to actually work. Compared with the KEMIMOTO Hardshell 22L, this soft design carries awkward loads more easily but sacrifices impact protection. The ergonomic support straps matter most on rides over an hour, where cheaper flat-strap bags start digging into shoulders.
Pros:- Dedicated helmet compartment fits most helmet types
- Included rain cover beats splash-resistant rivals in real downpours
- USB port keeps devices charged on long rides
- Ergonomic support straps reduce neck strain on tours
Cons:- Bulky and heavy when fully loaded
- USB port is useless without supplying your own power bank
Best for: Daily commuters and weekend tourers who carry a helmet, gadgets, and a power bank in all weather
Not ideal for: Riders doing short city hops — the 37L footprint and loaded weight feel excessive for a wallet and a lock
- Capacity:37L
- Material:Wear-resistant polyester
- USB Charging Port:Yes (external power source required)
- Waterproofing:Waterproof with included rain cover
- Helmet Storage:Dedicated helmet compartment
- Comfort:Ergonomic support straps
- Intended Use:Commuting, touring, outdoor adventures
Our verdict“If you can only buy one backpack that handles commuting, touring, and bad weather, this is the safest all-around bet.”
KEMIMOTO Motorcycle Backpack, Hardshell Helmet Backpack 22L Carbon Fiber Reflective Riding Bag
The hard carbon fiber shell is what separates this model from every soft bag here — it protects a laptop the way the KEMIMOTO 37L and the 45L Oxford fabric bag simply cannot. That rigidity comes with tradeoffs: the shell won’t stretch around odd-shaped loads, so packing flexibility is worse than the expandable soft designs. The reflective strips and streamlined profile make it a smart pick for urban riders in traffic, and the 7-inch expandable section closes most of the capacity gap to larger bags when needed. At 22L base capacity, it targets riders who carry a laptop and essentials rather than a full kit — the breathable mesh back keeps it comfortable through that daily routine.
Pros:- Hard shell offers real impact protection for electronics
- Expandable section adds up to 7.09 inches of storage
- Reflective strips improve night-riding visibility
- Lightweight with breathable mesh back panel
Cons:- Rigid shell limits packing flexibility for odd-shaped gear
- Narrow color selection
Best for: Urban commuters who carry a laptop and want impact protection plus night visibility
Not ideal for: Tourers or grocery-haulers — the rigid shell and modest base capacity fight against bulky, irregular loads
- Capacity:22L
- Dimensions:20 x 14 x 7 inches
- Expandable Length:7.09 inches
- Material:Carbon fiber hard shell
- Waterproof:Yes
- Visibility:Reflective strips
- Laptop Compartment:Yes
Our verdict“This is the pick if protecting a laptop matters more than maximizing cargo volume.”
Motorcycle Backpack, Waterproof with Reflective Strips for Riders
At 40L, this bag sits between the KEMIMOTO 37L and the 45L Oxford fabric model, but its real strength is organization — multiple compartments plus a helmet quick-attach system mean you can stow a helmet externally instead of sacrificing interior space like the 45L bag demands. The chest and waist straps are the standout comfort feature; they anchor the load at speed, which matters more than padding once you’re above 50 mph. The high-density nylon is splash-resistant rather than fully waterproof, so it trails the KEMIMOTO’s rain cover in sustained rain. Front and rear reflective strips cover visibility from both directions, something the hardshell KEMIMOTO only partially matches.
Pros:- Helmet quick-attach system frees up interior space
- Chest and waist straps keep the load stable at speed
- Front and rear reflective strips for two-way visibility
- Multiple compartments keep gear sorted on multi-day rides
Cons:- Only splash-resistant, not fully waterproof
- 40L bulk is awkward in urban settings
Best for: Long-distance riders who want a large, stable, well-organized load that doesn’t shift at highway speed
Not ideal for: Dense city commuters who squeeze between lanes — 40L of bulk is a liability in tight traffic
- Capacity:40L
- Material:High-density nylon fabric
- Water Resistance:Water-splash resistant
- Reflective Strips:Front and rear
- Helmet Carry:Quick-attach system
- Compartments:Multiple
- Comfort:Breathable mesh padding, adjustable shoulder, chest, and waist straps
Our verdict“Buy this for multi-day rides where load stability and organization beat compactness.”
45L Waterproof Motorcycle Helmet Backpack Bag for Men
When volume is the deciding factor, nothing in this batch matches 45L. The 900D Oxford fabric is a step up in tear resistance from the high-density nylon on the 40L reflective model, which matters if the bag lives strapped to a bike or gets tossed around at stops. Adjustable straps plus a chest strap and waist belt keep that big load rideable, mirroring the 40L bag’s stability approach. The honest tradeoff is information: no stated weight or dimensions, and fewer documented extras than the KEMIMOTO 37L — no USB port, no rain cover mentioned, no laptop sleeve confirmed. Compared with the KEMIMOTO, you’re trading features and refinement for roughly 20% more raw space. That’s a good deal for tourers and a poor one for gadget-focused commuters.
Pros:- Largest capacity in the lineup at 45L
- 900D Oxford fabric resists both water and tearing
- Chest strap and waist belt keep heavy loads stable
- Breathable mesh padding on back and shoulders
Cons:- No published weight or dimensions to plan around
- Sparse feature documentation compared with rivals
- Potentially unwieldy for everyday use
Best for: Touring riders and multi-day travelers who prioritize maximum cargo space over features
Not ideal for: Commuters who want charging ports, rain covers, or laptop sleeves — none of those are confirmed here
- Capacity:45L
- Material:900D Oxford & polyester fabric
- Water Resistance:Water-resistant
- Tear Resistance:Tear-resistant
- Helmet Fit:Accommodates full-face helmets and riding gear
- Adjustability:Adjustable straps, chest strap, waist belt
- Comfort:Breathable mesh padding on back and shoulder straps
Our verdict“Choose this only if sheer capacity is your top requirement and extra features don’t matter.”
Riderbag Reflective Motorcycle Backpack, Hi Viz Commuter Riding Bag
The hi-vis reflective panels here go further than the strip-level reflectivity on the KEMIMOTO Hardshell or the 40L nylon bag — this is a whole-surface visibility strategy aimed squarely at riders who share lanes with distracted drivers. At 35L with a helmet holder and multiple compartments, it covers a full commute, and the ventilated padding plus water pockets suit daily use rather than one big touring push. Compared with the KEMIMOTO 37L, it gives up the rain cover and USB port in exchange for lighter weight and a more ergonomic daily-carry shape. Weather resistance is adequate for commutes but not multi-hour downpours. This model makes the most sense for riders whose number-one gear decision is being seen.
Pros:- Hi-vis reflective panels deliver the strongest visibility in the lineup
- Helmet holder adds convenience without eating interior space
- Multiple compartments plus water pockets suit daily routines
- Lightweight, ergonomic build with ventilated padding
Cons:- Less weather protection than bags with dedicated rain covers
- Bulky for quick short trips
Best for: City commuters in heavy traffic who want maximum visibility and a comfortable daily-carry form factor
Not ideal for: All-weather tourers — weather resistance and feature set fall short of the KEMIMOTO 37L for long trips
- Capacity:35L
- Visibility:Hi-vis reflective panels
- Helmet Carry:Helmet holder
- Storage:Multiple compartments, water pockets
- Comfort:Ventilated padding, adjustable straps
- Weather Resistance:Weather-resistant materials
- Intended Use:Motorcycle and bike commuting, long-distance rides
Our verdict“If drivers seeing you matters more than weatherproofing or gadgets, this is the commuter bag to buy.”
Riderbag Reflective Motorcycle Backpack, Hi Viz Commuter Riding Bag
Where most bags in this roundup treat reflectivity as an afterthought, the Riderbag puts visibility first — hi viz panels cover the entire exterior, not just thin strips like on the 40L Helmet Holder Backpack. For riders who commute in early darkness or fog, that difference is the whole point. The 35L capacity sits comfortably between the compact KEMIMOTO 20L and the bulkier 40L options, hitting a middle ground for daily laptop-and-tools carry. Ventilated back padding also makes it more comfortable in summer than the hard-shell options.
The tradeoff is specialization: compared with the 40L Water-Resistant model, its weather resistance is lighter duty, and the bag can feel oversized for quick errands. Color options are limited, so riders wanting a low-profile look should look elsewhere.
Pros:- Hi viz reflective panels deliver visibility well beyond standard reflective strips
- 35L capacity balances daily-carry needs without being oversized
- Ventilated back padding improves comfort on warm-weather commutes
- Helmet holder adds convenience when walking off the bike
Cons:- Weather resistance is lighter duty than hard-shell or rain-cover-equipped competitors
- Can feel bulky for short trips or minimal loads
Best for: Urban commuters who ride in low light or heavy traffic and want maximum visibility
Not ideal for: Riders who want a stealth all-black look or need heavy-rain-grade weather protection without adding a cover
- Capacity:35L
- Visibility:Hi viz reflective panels
- Helmet Carry:Helmet holder included
- Storage:Multiple compartments and water pockets
- Comfort:Ventilated back padding, adjustable straps
- Weather Protection:Weather-resistant materials
Our verdict“This is the pick for riders whose top priority is being seen, especially on dark or foggy commutes.”
Motorcycle Backpack with Helmet Holder, 40L Water-Resistant Riding Backpack
This 40L model earns its place through structural ambition: a hard-shell main compartment swallows most full-face, modular, and even off-road helmets — broader compatibility than the softer nylon options like the Waterproof Helmet Bag. Add a padded 15-inch laptop sleeve and sealed seams with waterproof zippers, and it functions as a genuine work-travel bag rather than just riding gear. The full-length reflective strips give it better nighttime presence than most, though still short of the Riderbag’s total hi viz treatment.
The rigid shell is the compromise. Unlike fabric packs such as the KEMIMOTO 20L, it won’t compress when half-empty, and it still needs a rain cover in sustained downpours despite the sealed construction. Laptop users beyond 15 inches are out of luck.
Pros:- Hard-shell compartment fits nearly every helmet type including off-road and rally
- Sealed seams and waterproof zippers exceed typical water-resistant builds
- Dedicated padded laptop sleeve makes it work-ready
- GRS-certified recycled construction
Cons:- Not submersible; heavy rain still demands a rain cover
- Rigid shell sacrifices the packability of fabric alternatives
- Laptop sleeve limited to 15 inches
Best for: Riders who commute with a laptop and helmet and want one bag for riding, work, and travel
Not ideal for: Minimalist riders — the hard shell stays bulky even when nearly empty
- Capacity:40L
- Material:Water-resistant polyester and nylon, GRS-certified recycled
- Helmet Compatibility:Full-face, modular, open-face, off-road, rally
- Laptop Fit:Up to 15 inches
- Visibility:Full-length reflective strips
- Weather Protection:Waterproof zippers and sealed seams
Our verdict“The most versatile big-capacity choice here for riders blending daily commuting with real travel needs.”
Motorcycle Backpack for Men and Women, Waterproof Helmet Bag, Bookbag for Riding and Outings
This bag competes directly with the 40L hard-shell model above, and its argument is simple: similar capacity at a friendlier price, with more everyday flexibility. The soft high-density nylon build means it works as a school or gym bookbag the other six days of the week — something the rigid hard-shell can’t manage. At just 0.65 kg, it’s noticeably lighter, and its four pockets and three compartments keep a 15.6-inch laptop and clothing organized.
But the savings show where you’d expect. Water resistance here is coating-level, not the sealed-seam construction of the 40L Helmet Holder Backpack, so sustained rain is a genuine risk to electronics. Reflective strips exist but are modest compared with the Riderbag’s full hi viz approach.
Pros:- Featherweight at 0.65 kg, lighter than hard-shell rivals
- 40L capacity with organized pockets for mixed daily use
- Fits laptops up to 15.6 inches — larger than the 40L hard-shell allows
- Tear-resistant nylon holds up to daily wear
Cons:- Water-resistant only; no sealed seams or rain cover for heavy rain
- Generic design lacks the riding-specific comfort features of pricier options
Best for: Students and part-time riders who want one affordable bag for riding, school, and everyday use
Not ideal for: Riders who regularly face heavy rain — water resistance won’t protect electronics in a downpour
- Capacity:40 liters
- Dimensions:50 x 36 x 20 cm
- Weight:0.65 kg
- Material:High-density nylon, polyester
- Pockets / Compartments:4 pockets, 3 compartments
- Max Device Size:15.6 inches
- Safety:Reflective strips
Our verdict“A sensible value play for casual riders who need a do-everything bag rather than dedicated riding gear.”
Motorcycle Helmet Backpack, Waterproof Riding Backpack for Men
This is the no-frills entry of the batch: no laptop sleeve, no rain cover, no expandable net — just a large main cavity that fits full-face helmets, gloves, and clothes, built from tear-resistant high-density nylon. Compared with the KEMIMOTO 20L, it trades riding-specific design touches for raw internal space, which matters if your bag mostly carries gear rather than electronics. Reflective strips cover the night-riding basics.
The honest drawback is documentation, not construction: the listing gives no dimensions or weight, so sizing your helmet and judging pack feel requires a gamble. The single main pocket with three compartments also offers less organization than the Bookbag Helmet Bag’s four-pocket layout. Riders who like knowing exact specs before buying should weigh that uncertainty against the low price.
Pros:- Large main compartment handles full-face helmets plus daily essentials
- Waterproof and tear-resistant nylon construction
- Reflective strips support night-riding visibility
- Straightforward layout with three organizing compartments
Cons:- No published dimensions or weight specs to verify fit
- Lacks comfort details like ventilated padding found on rivals
Best for: Budget-minded riders who need a simple, spacious bag to haul a helmet and gear
Not ideal for: Detail-driven buyers — missing dimensions and weight specs make pre-purchase planning difficult
- Capacity:Large (helmet plus essentials)
- Material:High-density nylon
- Weather Protection:Waterproof, tear-resistant
- Safety:Reflective strip
- Organization:1 main pocket, 3 compartments, 2 zippers
- Helmet Fit:Full-face helmets, gloves, clothes
Our verdict“A capable basic hauler for riders who value capacity and simplicity over specs and refinement.”
KEMIMOTO Motorcycle Helmet Backpack, 20L Storage Bag with Expandable Hidden Net
Most bags in this roundup chase capacity; the KEMIMOTO 20L chases fit. The expandable hidden net stretches to cradle a full-face or modular helmet externally, so the interior stays free for a 14-inch laptop and gear — a smarter arrangement than the Oumurs 50L’s brute-force approach of stuffing everything inside. Reinforced stitching and padded straps suggest a bag built for daily use rather than occasional trips, and at 20L it never becomes the bloated liability that fully loaded 40L bags can be on a bike.
The limits are real, though. Weekend travelers will find 20L tight compared with the Basic Helmet Hauler or the 40L hard-shell, and the 14-inch laptop ceiling excludes larger machines. When the net is deployed with a big helmet, the profile grows bulkier than the bare specs suggest.
Pros:- Expandable hidden net carries helmets externally without eating interior space
- Compact 20L size stays comfortable and unobtrusive on the bike
- Reinforced stitching and water-resistant materials built for daily use
- Padded adjustable straps suited to full riding days
Cons:- Capacity is tight for trips longer than a commute
- Laptop compartment capped at 14 inches
- External net adds bulk when hauling a full-face helmet
Best for: Daily commuters who want a trim, well-built bag that carries a helmet externally and a laptop inside
Not ideal for: Touring riders or overpackers — 20L plus a 14-inch laptop cap is simply too small
- Capacity:20 liters
- Helmet Fit:Full-face or modular (external net)
- Laptop Fit:Up to 14 inches
- Key Feature:Expandable hidden net
- Material:Water-resistant with reinforced stitching
- Comfort:Padded adjustable straps
Our verdict“The right-size choice for commuters who want helmet carry without a 40L bag dominating their back.”
Oumurs Motorcycle Helmet Backpack 50L
Capacity is the whole story here. At 50 liters with an expandable design, this Oumurs pack out-hauls nearly everything in this roundup — the KEMIMOTO 35L looks modest by comparison, and even the 45L Waterproof Bag falls short once you factor in the dual-holding helmet system and multiple compartments. The included rain cover and 1680D Oxford fabric mean weather protection isn’t an afterthought, and the ventilated back panel matters when you’re carrying this much weight for hours.
The tradeoff is honest: a fully loaded 50L backpack is genuinely bulky, and this model gets heavy fast. For a daily city commute, it’s more bag than the job requires. But for touring riders and multi-day trips, nothing else in this lineup swallows gear as easily.
Pros:- Largest capacity in this lineup with expandable design
- Rain cover and water-resistant 1680D fabric for real weather protection
- Ventilated back panel and padded straps for long rides
- Multiple compartments keep riding and travel gear separated
Cons:- Bulky and awkward when fully expanded
- Heavy once loaded with gear plus a helmet
Best for: Touring riders and multi-day travelers who need to carry a helmet, gear changes, and luggage in one pack
Not ideal for: Daily short-distance commuters — the 50L footprint is oversized for a laptop-and-lunch load
- Capacity:50L
- Material:1680D Oxford fabric
- Waterproof:Yes, with included rain cover
- Helmet Carrying:Dual-holding system with helmet strap
- Extras:USB charging port
- Back Panel:Ventilated with padded straps
- Color:Black
Our verdict“Buy this if your trips are measured in days, not miles — it’s the closest thing to luggage you can wear on a bike.”
45L Waterproof Motorcycle Helmet Backpack Bag for Men
This 45L pack earns its spot by doing the fundamentals well without charging for frills. Where the Oumurs 50L adds a USB port and expansion system you may never use, this bag concentrates on load stability: a chest strap and waist belt that keep 45 liters of gear from shifting mid-corner — something no other bag in this batch matches as completely. The breathable mesh padding on both the back and shoulder straps makes longer rides more tolerable than the firmer panels on cheaper options.
The fabric is 900D Oxford rather than the 1680D used by the Oumurs and the 40L reflective pack, so it’s slightly less abrasion-resistant, and there’s no dedicated laptop sleeve. It’s also arguably too much bag for quick errands. But for riders who want maximum carrying security per dollar, this is the strongest value in the lineup.
Pros:- Chest strap and waist belt keep heavy loads stable while riding
- Breathable mesh padding on back and straps for extended wear
- Tear-resistant, water-resistant 900D Oxford and polyester build
- 45L capacity fits a full helmet plus riding gear
Cons:- Lower-denier fabric than 1680D competitors
- No dedicated laptop or electronics compartment
Best for: Budget-minded riders who haul a lot of gear and want chest and waist stabilization without paying for premium extras
Not ideal for: Laptop commuters — there’s no padded device compartment, and the size is overkill for office runs
- Capacity:45L
- Material:900D Oxford & Polyester
- Water Resistance:Water-resistant
- Adjustability:Adjustable shoulder straps, chest strap, waist belt
- Padding:Breathable mesh on back and shoulder straps
- Helmet Fit:Accommodates helmets and riding gear
Our verdict“The smart pick if stabilization and capacity matter more to you than premium fabric or tech features.”
KEMIMOTO Motorcycle Helmet Backpack, 35L
Sitting between the compact KEMIMOTO 20L and the oversized Oumurs 50L, this 35L version finds the middle ground most riders actually live in. The standout feature is the hidden expandable net — deploy it for a grocery run or spare layer, tuck it away when you want the bag to ride clean and low. That flexibility is what the fixed-capacity 45L Waterproof Bag can’t offer, and it’s why this model works as an everyday carry rather than a trip-specific tool.
The dedicated helmet compartment protects your lid instead of letting it bang around loose, which cheaper single-pocket bags don’t manage. The catch: 35 liters fully loaded still bulks up noticeably, and the motorcycle-specific layout — helmet holder, expandable net, riding-oriented compartments — makes it an awkward choice for anyone who isn’t on two wheels most days.
Pros:- 35L hits the sweet spot between compact and large-capacity bags
- Hidden expandable net adds flexible storage only when needed
- Dedicated helmet compartment protects headgear in transit
- Versatile enough for commuting, travel, and general outdoor use
Cons:- Gets bulky when fully loaded
- Motorcycle-specific design limits appeal for everyday non-riding use
Best for: Regular commuters and weekend riders who want one pack that flexes between daily carry and occasional gear-hauling duty
Not ideal for: Non-riders or occasional motorcyclists — the specialized helmet and net design goes unused off the bike
- Capacity:35L
- Expandable Hidden Net:Yes
- Helmet Holder:Yes, dedicated compartment
- Compartments:Multiple
- Intended Use:Commuting, travel, outdoor activities
Our verdict“The best all-rounder for riders who want one bag that adapts to the ride rather than being built for one scenario.”
Motorcycle Helmet Backpack with Rain Cover, 40L
This 40L pack differentiates itself on two fronts the others treat as afterthoughts: night visibility and laptop protection. The reflective strips and reflective-panel colorway address a real risk the KEMIMOTO 35L and the 45L Waterproof Bag simply ignore — being seen from behind at night. Add a padded sleeve that swallows a 17-inch laptop, and this becomes the only bag here that genuinely serves a working commuter carrying both a helmet and a computer.
The construction matches the premium intent: 1680D Oxford fabric, a rain cover, and compatibility with full-face, dual-sport, and off-road helmets. Tradeoffs exist, though. Like the Oumurs, it runs heavy when fully loaded, and 40 liters plus a laptop is a lot of bag for tight urban riding. Riderbag’s hi-viz options still beat it on outright visibility, but nothing else here combines reflectivity, waterproofing, and tech storage this completely.
Pros:- Reflective strips and logo for genuine night-riding visibility
- Padded compartment fits laptops up to 17 inches
- Fits full-face, dual-sport, and off-road helmets
- Waterproof 1680D Oxford build with rain cover included
Cons:- Heavy and bulky when carrying both laptop and helmet
- Only two color choices available
Best for: Working commuters who carry a laptop and helmet daily and ride home after dark
Not ideal for: Minimalist city riders — 40L plus laptop weight feels cumbersome on short, dense urban routes
- Capacity:40L
- Material:1680D Oxford fabric
- Waterproof:Yes, with rain cover
- Helmet Compatibility:Full-face, dual-sport, off-road
- Laptop Compartment:Padded, up to 17 inches
- Reflective Elements:Reflective strips and logo
- Color Options:Black with reflective logo, Grey with reflective panel
Our verdict“The clear choice if your ride home happens after sunset and your bag needs to carry a laptop as seriously as a helmet.”
How We Picked
I evaluated each backpack against four criteria that actually matter on a motorcycle, not on a product page. Weather protection came first: fabric denier alone tells you little, so I prioritized packs with welded seams, included rain covers, or proven waterproof materials over marketing claims. Helmet-carry capability came second — a real motorcycle backpack must stow or strap a full-face helmet without unbalancing the rider, and expandable nets or dedicated compartments earned higher marks than generic oversized openings.
Riding ergonomics was the third filter: chest straps, padded back panels, aerodynamic profiles, and load stability at highway speed separate riding-specific packs from repurposed school bags. Finally, I weighed value per dollar, which explains why two near-identical 45L budget bags rank mid-pack — they deliver capacity but cut corners on strap quality and visibility. Products are ordered by how well they balance all four criteria rather than by price or size alone, with specialist picks (visibility, hardshell commuting, maximum cargo) ranked for the rider they suit best.
Factors to Consider When Choosing Motorcycle Gear Backpacks
Choosing between motorcycle gear backpacks comes down to matching the pack’s strengths to how you actually ride. Before spending anything, work through these factors — they explain most of the price and quality differences in this roundup.Waterproof Claims Versus Waterproof Reality
The single most common mistake buyers make is trusting the word ‘waterproof’ on a listing. Most packs in this category use 1680D Oxford fabric with a polyurethane coating, which handles drizzle and road spray but lets water in through zippers and seams during sustained rain. A separately included rain cover is worth more than any fabric rating, because it protects the failure points — zips, stitching, and zipper flaps — that coatings cannot. If you commute year-round, treat a rain cover as non-negotiable and skip packs that omit one. Another trap: water-resistant is not waterproof, and the difference becomes obvious about ten minutes into a highway downpour at 60 mph, when water is forced into every seam. Buyers in dry climates can safely save money here; daily commuters cannot.
Real Capacity Versus Marketing Capacity
Capacity numbers in this category are measured fully expanded, which means a ’45L’ backpack may function as a 25L pack on your daily ride. Expandable designs are genuinely useful — they let a commuter run slim during the week and huge on weekend trips — but you should check the collapsed volume before buying. Also consider where capacity sits: tall, narrow packs are more aerodynamic and stable at speed, while wide, boxy designs catch wind and pull on your shoulders above 50 mph. Anything over about 35L worn on your back starts to behave like a sail, which is why many long-distance riders eventually move to tail bags or panniers. A backpack over 40L makes sense mainly for riders who park in places where luggage can’t stay on the bike.
Hardshell Versus Softshell Construction
This is the fork in the road most riders don’t realize exists until they’ve bought the wrong one. Hardshell packs hold their shape at speed, protect laptops and cameras from impact, and reduce fatigue because the rigid shell doesn’t deform against your back — but they can’t expand, and their fixed volume is all you get. Softshell packs flex, expand, and often cost less, making them better for irregular cargo like a spare visor, gloves, or a half-lid helmet. The deciding question is what’s inside: if you regularly carry electronics, the hardshell’s protection justifies its limits. If your load is clothes and gear, softshell versatility wins. Riders who carry both should look at the hybrid approach — a padded laptop sleeve inside a softshell expandable bag — which several picks in this roundup take.
Visibility Features for City Riding
Visibility is the most underweighted factor in buying decisions, and one of the cheapest to get right. A pack’s rear panel occupies prime real estate directly in the sightline of the driver behind you, and hi-viz colors with 360-degree reflective piping measurably improve how soon drivers register you at night. Many budget bags include a couple of reflective strips as an afterthought — visible head-on but invisible from the sides, where lane-change collisions happen. If you commute in urban traffic after dark, a dedicated hi-viz pack outperforms any accessory light you might clip on later. Sport and touring riders who spend most of their time in daylight flow can deprioritize this and spend the difference on weather protection instead.
Strap Systems and Load Stability
A backpack that shifts at speed is a genuine safety issue, not a comfort complaint. Look for a sternum strap to stop shoulder straps flapping in wind, and preferably a waist strap that transfers weight off your shoulders on longer rides. Pay attention to strap padding quality too — this is where budget bags cut costs, and thin straps dig in painfully once you load the pack past two-thirds capacity. External helmet nets sound convenient but act like a parachute when loaded with a full-face helmet at highway speeds, so riders who spend time above 45 mph should favor packs with internal helmet storage. Finally, check whether the back panel is contoured: flat panels press against your riding jacket’s armor and get uncomfortable within the hour.
When to Pay More (and When Not To)
Premium pricing in this category buys three things: genuine waterproof construction, better zippers and hardware, and smarter load distribution. Those upgrades matter for daily commuters and touring riders, whose packs get zipped open thousands of times a year and ride through every season. They matter far less for a weekend rider who covers dry-weather miles a few months a year — a $40 water-resistant pack with decent straps will serve that rider fine. The clearest waste of money is paying premium prices for mid-tier features: a $70 bag with no rain cover, mediocre straps, and thin reflective detailing is worse value than a well-designed $45 one. Match your spend to your mileage, not to the feature list.
Frequently Asked Questions
Can a motorcycle backpack actually hold a full-face helmet?
Some can, but the mechanism matters more than the claim. Packs with a dedicated internal helmet compartment or an expandable hidden net — like the KEMIMOTO 20L and 35L models in this roundup — carry a full-face helmet securely without consuming your main storage space. Generic oversized bags technically fit a helmet inside, but then you’ve used most of your capacity on a single item. One caution: helmets carried in external nets act like a sail at highway speeds and stress the straps, so internal storage is the better choice for riders who spend time above 45 mph. If helmet transport is your primary need, buy a pack designed around it rather than a big bag that happens to fit one.
Is a 40L or 50L backpack too big to ride with?
For most riders, yes — at least as a daily carry. Bags above roughly 35L catch substantial wind, pull on your shoulders at highway speed, and raise your center of gravity in corners. Those large sizes make sense when they’re expandable designs you run collapsed most days, like the Oumurs 50L, inflating only for trips. The practical ceiling also depends on your bike: a naked bike or cruiser with an upright riding position handles a big pack better than a sportbike with a forward lean, where the pack sits high and catches even more air. If you regularly need 40L or more, a tail bag or top box is usually the smarter long-term solution, with the backpack reserved for off-bike carrying.
Are USB charging ports on these backpacks actually useful on a motorcycle?
Mostly as a battery-pass-through, not a charger. The USB port on packs like the KEMIMOTO 37L and Oumurs 50L is just an external cable outlet — you supply a power bank inside the bag, and the port lets you charge a phone without opening it. That’s genuinely convenient for commuters who arrive with a dead phone, but the port does nothing on its own, and some riders find the pass-through flap lets in water. A better solution for riding is often a handlebar or tank-mounted USB charger wired to the bike, which charges while you ride rather than while you walk. Treat the backpack USB port as a nice off-bike feature rather than a reason to choose one pack over another.
What’s better for commuting: a hardshell or a softshell motorcycle backpack?
If your commute involves a laptop and highway speeds, hardshell wins — the rigid shell doesn’t deform under wind pressure, keeps the load stable, and protects electronics if you drop the pack or go down slowly. The KEMIMOTO 22L carbon-fiber hardshell in this roundup is built exactly for that rider. Softshell makes more sense when your cargo is irregular: gloves, a change of clothes, groceries, or a spare visor all fit better in a flexible, expandable bag. The honest tradeoff is that hardshells are one-size-fits-your-stuff — no expansion, no overstuffing — while softshells eventually sag and lose shape with heavy use. Commuters carrying both a laptop and bulky gear may prefer a softshell with a padded sleeve as the compromise.
How much should I spend on a motorcycle backpack, and what do I lose by going cheap?
Under $40 gets you capacity and basic water resistance, but expect thin straps, generic zippers, and minimal reflective detailing — fine for occasional fair-weather rides. The $40–70 range is where this category delivers its best value, adding rain covers, helmet-specific features, and visibly better hardware, which is why several of my top-ranked picks sit there. Above $70 you’re paying for true waterproof construction, hi-viz materials, and load-carrying ergonomics that hold up to daily use. The most expensive mistake isn’t buying cheap — it’s buying mid-priced with premium expectations. A rider doing 10,000 commuter miles a year should invest properly; a weekend rider honestly doesn’t need to.
Conclusion
Matching the right backpack to your riding comes down to three honest questions: how far you ride, what you carry, and what weather you ride through. Best overall goes to the KEMIMOTO 37L — its rain cover, real helmet capacity, and balanced ergonomics suit the widest range of riders. Best value is the Motorcycle Backpack with Helmet Holder, 40L, which delivers nearly everything the pricier packs offer at a budget price. Best for commuting is the KEMIMOTO 22L Hardshell, with its protective shell and laptop compartment built for daily electronics-toting riders, while the Oumurs 50L takes best for touring and long trips thanks to its expandable cargo volume.
For specific needs: the Riderbag Hi Viz models are the clear pick for night-time city commuters who put visibility first, and the KEMIMOTO 20L with expandable helmet net is the right entry point for beginners who mainly want a simple way to carry their helmet. New riders should start smaller and cheaper than they think they need — you’ll learn your real carrying habits within a month, and can upgrade with that knowledge instead of guessing up front.
