10 Best Waterproof Motorcycle Backpacks in 2026

An 18-liter capacity split between a waterproof roll-top main body and a zip-access rear compartment means you can separate wet rain gear from dry clothes without rummaging. The Quadloc-Lite harness shifts weight off your shoulders onto your chest and torso, which makes a real difference on long rides when every mile adds fatigue. Built from 420D Cordura Lite Plus with YKK zippers, this pack is designed to shrug off weather and road grit, so your phone, wallet, and layers stay dry even in a downpour. It suits riders who value waterproof integrity and comfort over sheer volume, and who want a bag that feels planted on their back at highway speeds.

At 3.1 pounds, the Trail 18 is heavier than the Kriega R22, which weighs 1.0 pound. That extra heft comes from the burlier fabric and harness system, so you gain durability and load management but lose some lightness for short hops. The Trail 18 does not include a dedicated laptop sleeve or helmet carry loop, features found on some other packs in this guide. So if your daily ride includes a laptop or you need to stash a helmet, you will need to pack creatively.

The main compartment holds 18 liters and the front pocket adds 4 liters, giving you 22 liters of waterproof storage. The Air Mesh back panel is designed to maximize airflow, and the Quadloc-Lite harness shifts weight from your shoulders to your chest and torso. That combination makes this pack a focused option for riders who want reduced back strain and better airflow during long rides. The removable white-taped liner makes cleaning simple and helps you spot small items quickly inside the main compartment.

The trade-off is that 22 liters is on the smaller side compared to the GEVINFA’s 40-liter capacity, so if you regularly carry a helmet or bulky overnight gear, you’ll outgrow this pack quickly. At just one pound it’s impressively light, but the minimal structure means it may not feel as supportive with very heavy loads as a heavier, more rigid pack would. For day trips, commuting, or spirited canyon rides where airflow and comfort matter more than max capacity, this is a smart, focused design that delivers exactly what it promises.

At only 1.3 pounds and 20 liters, this backpack keeps things light and focused on one job: getting your helmet off your head and onto your back. The DHT System gives you two ways to carry up to two helmets, an elastic cover on the front and a side strap. So you can stash your primary lid and a passenger helmet without awkwardly bungee-cording anything. That makes it a natural fit for daily commuters or short weekend rides who want to walk into a coffee shop or office without helmet in hand, and the padded 13-inch laptop compartment means you can bring work along too.

Twenty liters won’t swallow a change of clothes, lunch, and a tablet for a full workday plus gym gear all at once. The 600D polyester and waterproof zippers handle rain well, and the included rain cover adds a second layer for downpours. But there’s no hardshell protection if you toss it in a truck bed or drop it on concrete. If your priority is helmet-free convenience over maximum cargo space, this is a smart, purpose-built pick.

With dimensions of 19.7 by 14.2 by 7.9 inches, this bag fits most full-face helmets and a 15-inch laptop, making it a practical choice for riders who need to carry both. The high-density waterproof nylon fabric with sealed zippers keeps gear dry in rain, so you can ride through a downpour without worrying about soggy contents. It’s built for riders who want one bag that handles both the commute and longer hauls.

Size is the main consideration: at 19.7 inches wide and 7.9 inches tall, it’s a sizable bag that may not fit as easily behind a small windscreen or feel as compact on a sportbike. The chest and side straps help keep the load stable, but they add an extra step when putting on the bag. If you regularly carry a helmet plus gear and don’t mind the extra bulk, this bag gives you plenty of room for the weight.

The 22-liter capacity works for daily commuting, though it’s smaller than the GEVINFA 40L bag if you need to carry extra gear. An expansion zipper lets you increase storage to hold a helmet, but the rigid shell limits how much you can cram in compared to a fabric pack. For riders who value protection and a secure fit on the bike, this backpack is a practical choice.

A hidden external mesh pocket that can hold a helmet or ball means you don’t have to stuff your lid inside the main compartment, freeing up the interior for a laptop, tablet, and daily gear. The included helmet rain cover adds an extra layer of protection when that helmet is riding outside, and the reflective branding and strips help you stay visible on nighttime rides. This bag suits riders who need to carry a helmet externally while keeping the inside organized for work or travel gear.

Weight is the main trade-off: at 3.1 pounds, the Moman BM2 is noticeably heavier than lighter packs like the Kriega R22 (1.0 lb), which matters if you’re carrying it for long walks after parking. For riders who prioritize helmet storage and all-weather readiness over minimal weight, this is a practical choice.

A 40-liter main compartment means this backpack swallows a full-face helmet plus extra gear for a day trip, and the 1680D Oxford fabric is built for tear resistance and waterproofing. That heavy-duty build makes it a natural fit for riders who prioritize durability over weight savings. Someone who regularly hauls a helmet, laptop, and change of clothes on rough commutes or long-distance rides wants a bag that won’t fray at the seams after a season of use.

Weight is the main trade-off: at 2.9 pounds, it’s nearly three times heavier than the OG Original RoadRunner Small (1.3 lb) and significantly bulkier than the Kriega R22 (1.0 lb). If you’re counting every ounce for a sportbike trip or prefer a slim profile, those lighter options may serve better. But for riders who value a rugged, do-it-all pack that can double as a gym bag or ski boot carrier, the WINPRIM’s fabric and capacity justify the heft.

A 20-inch tall backpack with Molle webbing lets you strap pouches and tools to the outside, making it easy to customize your carry setup for long rides. The 900D waterproof fabric and included rain cover provide wet-weather protection, so your gear stays dry in rain. This bag works well for riders who want to add external storage and don’t mind a taller shape that fits bulky items like a jacket.

The 7-inch depth means you can’t pack as much as you might in a deeper backpack like the Kriega R22, which has an 8.6-inch depth. The Seibertron also lacks a dedicated helmet strap or laptop sleeve, so it’s less practical for daily commuters who need to carry a computer or secure a full-face helmet. If you value modular add-ons, this bag fits that need; if you want a lighter option, the Kriega R22 weighs 1.0 pounds.

A dedicated helmet strap system that fits full-face, half, and modular helmets means you can stop carrying your helmet by hand or leaving it on a mirror. The 20-liter capacity is enough for a change of clothes, some riding gear, and daily essentials, while the waterproof 300D Oxford cloth keeps everything dry in rain. This backpack suits riders who want a practical daypack that handles the helmet-carrying chore without adding bulk or complexity.

The 20-liter capacity is enough for a change of clothes, some riding gear, and daily essentials, but it is smaller than the 40-liter GEVINFA option listed in our guide. If you need to carry a laptop or pack for an overnight trip, you may find the JLDTOP limited. The backpack prioritizes helmet security with its adjustable strap system, making it a practical choice for commuting and short rides where convenience matters more than maximum storage. The USB port and reflective strips add everyday usability without overcomplicating the design.

The 20-liter capacity of the Oxford Atlas B-20 is modest, but the real story here is the modular G-hook connection system. This backpack is designed to lock into Oxford’s larger Atlas luggage line, so you can carry it on its own or clip it to a bigger bag for extra storage. It suits riders who want a flexible, expandable setup rather than a standalone everyday pack.

Twenty liters won’t hold a helmet or enough gear for a multi-day trip on its own. You’ll need to invest in the companion bags to get the full modular benefit. Compared to the Kriega R22, which offers a standalone design without a modular system, the Atlas demands more upfront planning. But if you value a system that grows with your load and appreciate the aluminum G-hooks and Duraflex hardware, this is a thoughtful, well-built choice for the modular-minded rider.
