See size chart

waterproof & ultralight compression dry sack.

Carry your down sleeping bag, extra clothing layers, or outdoor essentials in the ultra-lightweight, space-saving design of the SealLine Blocker Compression Dry Sack. This dry sack features lightweight, fully waterproof construction to keep your gear dry without adding excessive bulk to your pack or kayak storage area.

It's packing a PurgeAir valve that releases excess air trapped inside, so you're not carrying a bonafide balloon while backpacking or paddling long distances. Additionally, it features SealLine's Continuous Compression System, which tightens down uniformly to reduce carrying bulk, but without exerting tons of pressure on delicate seams that tend to break easily.
