DESCRIPTION

Outdoor Research did away with heavy, bulky valves and made the AirPurge Dry Compression Sack with a section of air-permeable fabric to maintain waterproof performance. Basically, you can fill this compression sack, close it, and cinch it down while air escapes from the breathable-but-still-waterproof fabric. Think of this Outdoor Research sack as a vacuum sealer for any gear you want to keep dry.
