Learn the proper technique for using a dry bag on the water. This guide covers roll-top closure, packing for balance, and securing your gear for kayaking or canoeing.
Quick answer
To use a dry bag for kayaking or canoeing, roll the top at least three times, squeeze out excess air, then clip the buckles. Pack heavier items low and toward the center of your boat for stability.
Why the right dry bag matters on the water
A dry bag is only as reliable as its construction. For paddle sports, you need a bag that resists abrasion from kayak cockpits, canoe gunwales, and gravel landings. The Big River Dry Bag uses 420D nylon with a TPU laminate that handles this abuse while keeping water out. Its reinforced seams and roll-top closure add another layer of security when waves splash over the deck.
Size also affects how you pack. A 20-liter bag works for day trips, while a 35- or 55-liter bag suits multi-day expeditions. Choose a size that fits your hatch or the space between your feet in a canoe without forcing the bag into a tight spot.
Common mistakes that let water in
The most frequent error is not rolling the top enough. One or two rolls may look fine but often leave a gap that lets water seep in during a capsize or heavy rain. Another mistake is packing the bag so full that you cannot roll the closure properly. Leave at least a hand-width of empty space at the top so the roll sits flat and the buckles can clip securely.
Also avoid stuffing the bag with sharp objects like a multitool or fishing hooks without a protective pouch. These can puncture the laminate over time.
How to pack and seal your dry bag for paddle sports
- 1. Choose the right size and pack strategically: Select a dry bag that fits your boat's storage space without being crammed. Place heavier items like a stove or food at the bottom and toward the center of the bag. Lighter items like clothing go on top. This lowers the center of gravity and keeps your kayak or canoe stable. A bag that is too large for the hatch may bulge and shift, affecting your boat's balance.
- 2. Remove excess air before sealing: After packing, press down gently on the bag to push out as much air as possible. Then, starting from the bottom of the roll-top opening, fold the fabric over itself three full turns. Each roll should be tight and even. The fewer air pockets inside, the less buoyant the bag will be if you capsize. Too much air left inside makes the bag float awkwardly and harder to secure in a hatch or under a canoe seat.
- 3. Clip the buckles and test the seal: Bring the side-release buckles together and snap them closed. The strap should be snug but not so tight that it deforms the roll. Give the bag a gentle squeeze—if you hear air escaping, the seal is not complete. Re-roll and try again. A properly sealed bag should feel firm and show no gaps at the fold. If the buckles are hard to clip, you likely rolled too few times or left too much air inside.
- 4. Secure the bag in your boat: In a kayak, place the dry bag in the hatch or behind the seat and use the bag's attachment points or a simple strap to keep it from sliding. In a canoe, wedge the bag between thwarts or under the seat. For whitewater, lash the bag to a thwart using a carabiner or cord. A loose bag can shift your center of gravity and make the boat harder to control. Even a waterproof bag is useless if it floats away after a capsize.
Gear that helps
- Big River Dry Bag: The Big River Dry Bag is made from rugged 420D nylon with a TPU laminate and has a waterproof roll-top closure with reinforced seam construction. This construction resists abrasion from kayak cockpits and canoe gunwales, and the roll-top seal keeps gear dry even after repeated wet landings or a capsize.
