The Evac is a waterproof compression dry bag from Sea to Summit that uses an air-permeable base to purge trapped air while the purge valve stays sealed against water. That lets you squeeze a sleeping bag or puffy jacket down much smaller than a standard roll-top dry bag, which only compresses what you can force out through the opening. It suits backpackers, bikepackers and paddlers who need bulk cut down and gear kept dry. Against plain compression sacks it adds real waterproofing; against heavier PVC dry bags it is lighter but the thin nylon needs more care around sharp edges.

Owners rate the Evac highly for cutting pack volume, especially for sleeping bags and down jackets, and report gear staying dry in rain and on the water. Complaints center on the thin fabric and the care needed to roll and seal it properly.
The Sea to Summit Evac Compression Dry Bag is a waterproof pack sack that works as both a dry sack and a compression sack. It holds 13 gallons and is made from nylon (polyamide).
