Product Details

Air compresses out, water can't get in-keep your bulky soft gear dry and compressed anywhere space is an issue. Our valve-free eVent Compression Dry Sack was the first of its kind, earning it a coveted Backpacker Editors' Choice Award in 2007-and it's still a winner today. Squish your bulky soft items down to one-third of their original volume and keep them dry. Made from a sturdy 70D PU-coated Nylon waterproof fabric in the body and lid, the eVent waterproof but air-permeable base allows air to be pushed out of the sack while stopping water getting in. This is a lighter, simpler and more reliable solution than a purge valve. The four compression straps provide space-saving even compression and the non-wicking roll-top closure delivers a reliably watertight seal.
