A 0.13-pound featherweight that has never leaked for years of owners.

At just 0.13 pounds, this 20-liter sack is the lightest way to keep your gear dry on a long climb. It is made from bluesign-approved 30D Ultra-Sil Cordura ripstop nylon with a slippery finish, so it slides into a pack without snagging. The 2,000mm waterhead rating means the fabric resists a serious column of water pressure.

The smooth, slippery material makes cramming gear into a pack easier — owners who bought multiple bags in different colors use them for color-coded organization. Owners mention the translucent fabric shows exactly what is inside, and the oval base resists rolling away on a slope. The patent-pending field repair buckle can be swapped in seconds if it ever breaks.

Compared to the Pelican’s 30L, this holds less at 20 liters, but it costs a fraction of the weight. The thin material is the honest trade-off: it is lightweight, not bulletproof, and a few customers note seams can rip under stress. For packing a quilt or a spare layer inside a pannier, this is the quiet workhorse.

A duffel-style dry bag that straps down tight and shrugs off a cross-country downpour.

This 30-liter tail bag is built from 500D waterproof mesh fabric that resists abrasion and tearing, standing up to heavy rain, snow, dust, and even brief submersion. The roll-top closure secures with reinforced straps — just roll two to three times, buckle, and go. A side air-release valve lets you squeeze out excess air to create more packing space.

What sets this apart is the mounting system: multiple sturdy buckles keep the bag firmly in place, and it includes 4 tie-down straps for lashing to a rack. Reflective strips on the sides boost visibility in low light, and the front MOLLE-compatible webbing lets you attach extra gear. Owners took it on a cross-country Harley run through heavy rain and found everything dry.

The internal divider bag enables dry-wet separation, so you can isolate a wet rain jacket from clean clothes. One honest note: the strap connectors are plastic, which a few owners expect may get brittle over time in harsh weather. At this capacity and price, it is a strong mid-range value.

A 10-liter under-seat pack that swallows a 50-mile ride’s worth of layers and snacks.

This saddle bag tucks neatly under your seat and holds everything you need for medium and long-distance rides. The inner bag uses a 3000mm waterhead waterproof fabric, and waterproof rubber strips at the seams let it withstand heavy rain. The cross elastic rope on top fixes a pump, wet clothes, or a helmet.

Installation is simple — four straps fix the bag at four points, and pressing the buckles after tightening reduces loosening from bumps. A reflective strap, brand logo, and tail light hook keep you visible at night. Owners find it holds rain jackets and snacks easily for 50+ mile rides, and the quality exceeds what the price suggests.

The honest trade-off is stability: the bag tends to sway during use, especially in wind or when riding out of the saddle. One owner noted that not tightening it well enough let the tire rub a hole in it. For road, mountain, and folding bikes, this is a solid compact choice — just cinch it down firmly.

This 48-liter duffel rode 2500 miles on a bikepacking trip and still looks brand new — the smooth PVC shell shrugs off scrapes and weather.

Roll the opening down and this 48-liter duffel becomes 100% waterproof — the manufacturer guarantees your gear stays dry, so a sudden downpour won’t soak your sleeping bag. You get three carry options: a velcro strap for handheld use, a backpack mode when you undo the velcro, and an included shoulder strap for cross-body carry, so you can switch from bike to trail without repacking.

Surface details are thoughtful: three reflective pieces for night safety, an air vent to compress the bag, and a waterproof postcard pocket with an inside opening so business cards stay dry. A zipped interior pocket holds electronics and small valuables. Reviewers point out a 60L unit survived 8+ hours in interstate rain and another took on torrential rain, hail, and dust without a drop inside.

The package includes 4 fixed straps and 1 shoulder strap. It is a heavy-duty option for riders who pack for extended travel.

A 50-liter tarpaulin duffel that kept a tent and clothes dry through 700 miles of abuse.

Built from high-grade tarpaulin with high-frequency welded seams, this 50-liter duffel delivers reliable waterproofing that owners trust on boats and bikes alike. The roll-top closure provides genuine confidence against water ingress. Four quick-release straps fasten it to motorcycles, boats, kayaks, and bikes in seconds.

Four high-brightness reflectors provide solid night-time visibility, and the 50L main compartment fits a tent plus clothes with room left over. One owner packed a week’s worth of outfits into the 50L model, using the interior mesh end pockets for essentials and side pockets for devices. The bag survived a 1000+ mile off-road adventure with everything staying dry.

The straps earn the most discussion — they work great as tie-downs, but owners note you have to position them just right or they loosen with bouncing. The 50L capacity puts this in the same class as the tacxmotorrad 48L, but the tarpaulin material and mesh pockets give it a different feel. For riders crossing rivers or hitting the beach, this is a standout.

A roll-top backpack that floats on water and comes with a certified phone case.

This 30-liter backpack uses 3-layer 500D PVC heavy-duty woven mesh with high-frequency stitching that leaves no pinholes, making it 100% waterproof and airtight. The roll-top closure with a single reinforced strip keeps water out — fold it down 3-4 times, buckle, and go. It is floatable, so if it goes overboard it stays on the surface for easy retrieval.

The standout feature is the included IPX8-certified 8-inch waterproof phone case that fits even the largest phones. Large splash-proof zippers on the outside provide quick access, while mesh pockets, a drawstring front, and a left-side storage pocket handle smaller items. The ergonomic breathable padded back panel takes the weight off your back for long hikes.

Owners took it through Costa Rica’s rainy season, kayaking in rain and into hot springs, with everything inside staying dry. A retaining buckle attaches the bag to a boat hull so rapids cannot sweep it away. Compared to the Pelican 30L, this floats and includes the phone case, but it is heavier at 1.44 kg.

An adjustable 7-14L handlebar roll that survived a 575-mile torture test.

This handlebar bag adjusts from 7 to 14 liters, letting you scale capacity for the trip. It secures with 5 fixed points: large straps, eight spacers, and 2 side-release buckles to the handlebars, plus a short strap to the head tube to prevent shaking. Four alloy hooks adjust the compression straps to protect your frame and brake cables.

The roll-down closure at each end makes it easy to find what you need, and two exterior straps let you attach extra gear or even a tent. Three reflective logos boost night visibility, external elastic cords secure wet raincoats or a photography tripod, and a strap storage loop keeps straps from catching in tires. Shoppers say true 14L capacity — it fits a CPAP, laptop, U-lock, sandals, and clothes — and it survived a 9-day, 575-mile trip without wheel interference.

The trade-off is access: the roll-top closure is cumbersome for frequent stops, and removal takes 1-2 minutes with 5 straps. This is not for commuters or novices; it is a dedicated bikepacking tool. The poor instructions are a recurring theme, so experienced riders will have an easier time.
