The Sea To Summit eVac Dry Sacks allow air to be squeezed out through the eVent base for valve-free air expulsion. Simply roll the sack down to squeeze out the air before closing the buckle. With an oval shaped base they are designed to fit the internal contours of a backpack.
Made from 70D nylon with a 10,000mm waterhead and double stitched and taped seams to ensure your gear stays protected. The non-wicking closure strip ensures moisture is not drawn into the bag when rolled shut.
