The eVent® Compression Dry Sack earned a Backpacker Editors' Choice Award in 2007, and there is no question that it's still a winner today.
 
Made from a sturdy 70D Nylon waterproof fabric in the body and lid, with an eVent® waterproof but air-permeable base that allows air to be pushed out of the sack. No need for a purge valve, making these lighter and simpler. The four compression straps, use hypalon roll-top non-wicking closure. These dry sacks are the epitome of durability, versatility, and compression.
