8 Best Cycling Backpack Dry Bags for 2025

Uncompromising dry protection meets all-day comfort in the UPWELL 30L, a ruggedly built backpack that stands tall where others falter. With 100% waterproof 500D vinyl-coated polyester and fully welded seams, this bag laughs in the face of downpours, submerged rapids, or accidental drops into lake water—your gear stays bone-dry no matter the scenario. The ergonomic sponge-padded back panel molds to your spine, reducing pressure during long hikes or bike commutes, while the roll-top closure with button-press seal ensures foolproof waterproofing every single time. If you’re tired of flimsy dry bags that leak or dig into your shoulders, this one solves both problems with surgical precision.

In real-world testing across kayaking trips and rainy trail hikes, the UPWELL 30L held its own with zero moisture ingress, even after being briefly submerged during a capsized paddle session. The 30-liter capacity easily swallowed a full change of clothes, towel, phone, and snacks, while the side mesh net kept a water bottle or umbrella handy without compromising security. On rough terrain or bumpy bike paths, the bag stayed stable thanks to its snug fit, though shoulder straps could use more padding for ultra-long hauls. It’s not the lightest option, but the trade-off is bulletproof durability—this bag won’t tear on brush or crack under UV exposure like thinner PVC models.

Compared to the HEETA 5L, the UPWELL is a full-service adventure pack, not just a splash-proof pouch. It doesn’t float quite as high as the Piscifun 20L, but it offers more storage and better back support for multi-hour use. Ideal for cyclists needing weatherproof cargo, weekend kayakers, or commuters braving monsoon seasons, this backpack delivers where reliability matters most. It costs more than budget picks, but you’re paying for proven waterproofing and comfort that outlasts cheaper rivals.

Transparency meets tactical efficiency in the HEETA 5L, a game-changer for quick-access water adventures. The crystal-clear PVC body lets you spot your phone, keys, or towel instantly, eliminating the frantic dig-through of opaque dry bags. Built with seamless welding and 0.6mm reinforced base, this mini backpack shrugs off splashes, rain, and brief dunks—perfect for paddleboarding or beach dashes. The touchscreen-compatible phone case included is a standout, letting you snap photos or check maps without breaking the seal. If you’re after a lightweight, no-fuss, highly visible dry bag for short trips, this one nails the brief.

During real-world paddleboard outings and poolside commutes, the HEETA 5L proved surprisingly resilient, keeping contents dry even after accidental drops in the water. The adjustable shoulder straps stayed comfortable for up to two hours, and the side handle made hand-carrying easy when switching activities. At just 5 liters, it’s not meant for full-day trips—think essentials only: phone, wallet, sunscreen, keys. It won’t float high under load, and prolonged submersion risks seepage, so it’s best for surface-level protection. But for its size, the ease of cleaning and instant visibility make it a joy to use.

Stacked against the AFISHTOUR 15L, the HEETA 5L is smaller but smarter for visibility and access. It lacks the packable design or cycling-specific fit of the AFISHTOUR, but for beachgoers, swimmers, or parents packing kids’ gear, the transparent build is a game-winning feature. It’s the most affordable in the lineup, yet punches above its weight in usability—ideal for those who value speed and simplicity over storage volume. You sacrifice capacity, but gain unmatched convenience for quick, wet-weather jaunts.

Engineered for paddlers who demand smart separation, the Piscifun 20L introduces a game-changing dry/wet compartment system that sets it apart from the pack. The main roll-top chamber stays 100% waterproof, while the front zippered pocket accepts wet towels or swimsuits—no more soggy socks contaminating your dry clothes. Constructed from 500D nylon with a floating design, this backpack pops to the surface if dropped overboard, a lifesaver during kayaking mishaps. Add in the included IPX8 phone case and bonus waist pouch, and you’ve got a kit that’s ready for real-world chaos right out of the box.

On extended kayaking trips, the Piscifun proved its worth: the dry/wet split worked flawlessly, keeping gear organized and odors contained. The 20-liter volume fit lunch, layers, and safety gear with room to spare, while the breathable shoulder straps reduced sweat buildup on hot days. It floated reliably, though strong currents could pull it under if unattended. The main seal is rock-solid when rolled properly, but the front zippered section is only splash-proof—don’t trust it with electronics. Still, for kayakers, rafters, or beach campers, this bag solves the #1 storage headache: mixing wet and dry items.

Compared to the IDRYBAG 20L, the Piscifun wins on organization and included extras, though both use similar roll-top tech. It’s not as packable as the AFISHTOUR, nor as spacious as the UPWELL 30L, but for dedicated water sports users, the wet/dry design is a masterstroke. It costs slightly more than basic models, but the thoughtful layout and floating safety net justify every penny—especially if you’re constantly hauling soaked gear.

Precision engineering meets rugged practicality in the IDRYBAG 20L, a no-nonsense workhorse built for cyclists and hikers who refuse to compromise on protection. Forged from 500D vinyl-coated polyester with welded seams, this bag laughs at torrential rain, river splashes, or muddy trail spills—your gear stays hermetically sealed and bone-dry. The roll-top closure with buckle lock is intuitive and secure, while the foldable side pouch keeps a water bottle within arm’s reach without breaking stride. Add integrated reflective strips, and you’ve got a night-riding cyclist’s dream: safe, visible, and fully protected.

In real-world mountain biking and kayak-to-hike missions, the IDRYBAG delivered flawless waterproofing—even after a full dunk during a river crossing. The 20L model strikes a sweet spot: roomy enough for layers, food, and tools, yet compact enough to avoid sway on technical trails. The shoulder straps are stable, though lack lumbar padding for all-day treks. The front zipper pocket is splash-proof only, so keep valuables in the main dry chamber. Still, for cyclists needing quick access, visibility, and bombproof sealing, this bag checks every box.

Versus the Earth Pak, the IDRYBAG is lighter and more cycling-friendly, though it lacks the padded waist belt and MOLLE system. It’s pricier than the HEETA but offers far superior durability and safety features. Ideal for commuters, bikepackers, and outdoor guides, it balances capacity, visibility, and protection like few others. You pay more than budget picks, but get a smarter, safer, and more road-ready design in return.

Where comfort meets command-grade durability, the Earth Pak stands as the gold standard for long-haul adventurers who won’t sacrifice support for waterproofing. Its ergonomic padded backpanel and contoured shoulder straps redistribute weight like a premium hiking pack, while the reinforced sternum strap and removable waist belt lock it in place during steep climbs or bumpy bike rides. The 100% waterproof roll-top closure has never leaked in testing—even after river drops—and the MOLLE-compatible D-rings let you clip on extra gear mid-trip. If you’re tired of dry bags that punish your back after two hours, this one rewrites the rules of endurance carry.

On multi-day bikepacking routes and rainy mountain hikes, the Earth Pak proved unmatched in load management. The interior mesh pocket and key ring kept small items organized, while the splash-proof exterior zip offered fast access to snacks or maps. At no extra weight penalty, it floats reasonably well and resists abrasion from rocky terrain. However, the lack of side bottle pockets means you’ll need a separate hydration setup. It’s not the most packable, but for serious outdoor users who hike, bike, or paddle for hours, this bag delivers pro-level comfort without trading protection.

Next to the STOVER 25L, the Earth Pak wins on padding and adjustability, though STOVER offers more internal pockets. It costs more than most, but you’re paying for a suspension system that feels like a high-end hiking backpack—rare in the dry bag world. Ideal for ultra-hikers, touring cyclists, or fishing guides, it’s the ultimate fusion of support and waterproof reliability. You trade some storage flexibility, but gain unmatched all-day wearability.

Maximum capacity meets motorcycle-ready toughness in the HEETA 80L, a beast of a dry bag built for weekend warriors and gear hoarders. With an 80-liter cavernous interior, it swallows sleeping bags, camping stoves, rain gear, and motorcycle tools like a vacuum—perfect for roof-rack-free road trips or boat expeditions. The thick 500D PVC and double-reinforced stress points laugh at scrapes, UV rays, and downpours, while the quick-squeeze air valve lets you compress bulky loads by up to 20%. When sealed, it’s fully waterproof against rain and splashes, though not for deep submersion.

In real-world use—packing for a three-day kayak-camping trip—the 80L handled everything: tent, dry clothes, food, and safety kit, all organized via eight D-rings and a wide-mouth opening. The removable padded straps converted it to a backpack with decent comfort, though long hikes aren’t its strength. On a motorcycle, it strapped securely and resisted flapping even at highway speeds. As a gym or travel duffel, it’s overkill, but for adventurers needing one bag to rule them all, it’s unbeatable in volume and ruggedness.

Compared to the UPWELL 30L, the HEETA 80L is four times the capacity with heavier-duty build, though far less portable for cycling. It lacks the floating ability of smaller packs, but excels where space and durability trump portability. Ideal for motorcyclists, rafting crews, or overlanders, it’s the king of storage without compromise. You pay a premium, but get a tank-like duffel that outlives lesser bags.

Organization is king in the STOVER 55L, a highly structured dry backpack that brings order to outdoor chaos. Unlike most roll-top bags that turn into black holes, this one features three internal pockets (one zippered), two mesh side pockets with straps, and a splash-proof front compartment—perfect for keys, GPS, or energy bars. The high-frequency bonded seams guarantee 100% waterproofing, and the floating design ensures recovery if dropped in water. Add a whistle on the sternum strap for emergencies, and you’ve got a safety-conscious adventurer’s dream.

In testing across multi-day fishing trips and bike-trek combos, the STOVER’s compartments shined: no more digging for sunscreen or losing small tools. The 55L model carried a full camping kit, and the adjustable padded straps distributed weight evenly, though the waist clip felt flimsy under max load. It floats reliably, seals tightly, and the front cargo straps let you lash on extra gear. But like all large dry bags, it’s awkward on narrow bike paths or crowded trails.

Versus the Earth Pak, the STOVER wins on pockets and internal layout, though Earth Pak offers better back support. It’s pricier than basic models, but you’re paying for smart storage and safety extras. Ideal for families, guides, or anyone hauling diverse gear, it’s the most organized dry backpack in the game. You trade some comfort, but gain unmatched accessibility and peace of mind.

Weight weenies and minimalist riders rejoice—the AFISHTOUR 15L is a featherlight 5 ounces that disappears in your pack until you need it. Crafted from military-grade TPU-coated nylon, it shrugs off rain, snow, and trail grime with impressive water resistance, though not full submersion protection. The roll-top closure seals tight, and the packable design folds into its own pocket, making it the ultimate emergency backpack for cyclists and day hikers. When unfurled, it holds a jacket, snacks, phone, and small tools—enough for sudden downpours or unplanned detours.

On mountain bike rides and alpine scrambles, the AFISHTOUR proved invaluable as a grab-and-go solution. The adjustable straps fit all sizes, and the 15L volume was perfect for essentials without bulk. It doesn’t float like PVC bags, and the material resists punctures but not sharp rocks. Still, for ultralight cyclists, skiers, or backpackers needing a spare dry sack, it’s unbeatable in portability and versatility.

Against the HEETA 5L, the AFISHTOUR offers more capacity and better cycling fit, though less visibility. It’s not for kayakers needing full waterproofing, but for adventurers who prioritize packability and weight, it’s the clear winner. You sacrifice floating and submersion proofing, but gain a near-invisible, always-ready companion.
