The Sea to Summit Evac is a 13-liter dry bag that also compresses its contents. Its eVent-style air-permeable base lets trapped air escape as you roll the top down, so you can squeeze a sleeping bag or puffy jacket small without fighting a balloon of air. The nylon body is fully waterproof and the roll-top closure keeps water out. It suits backpackers and bikepackers who need to shrink bulky insulation inside a pack. Against plain roll-top dry bags it packs down further; against heavier compression sacks it stays lighter and doubles as a waterproof liner.
