Nautical 20L Waterproof Dry Bag Backpack – Built for Sea & Storm

Wherever the tide takes you, the Nautical 20L Waterproof Dry Bag Backpack keeps your gear dry, secure and adventure-ready. Made from rugged 500D PVC tarpaulin, this IPX6-rated waterproof backpack stands up to wind, waves and sudden downpours—protecting your essentials from water, dirt, sand and snow.

Ideal for paddleboarding, sailing, kayaking, beach days and travel, this 20-litre dry bag features a secure roll-top closure, detachable padded shoulder straps, and an internal zippered mesh pocket for stashing valuables. Roll the top at least 3 times and clip to seal—your gear stays bone dry and buoyant, even if your bag hits the water.

With reinforced D-rings, a carabiner, and a front rubber handle, this waterproof backpack gives you everything you need for comfortable carry and quick access on the go.
