Sea to Summit Evac Lightweight Dry Bag

The Evac Lightweight Dry Bag uses Sea to Summit's eVac base, an air-permeable but waterproof panel that lets you push trapped air out as you roll the top closed, so the bag packs down smaller without letting water in. The body is recycled 70D nylon with a light-reflecting interior for finding items by torchlight. It suits packing clothing, sleep gear or electronics where a genuinely waterproof liner matters, such as canoeing or wet weather; the eVac base's main advantage over a standard dry bag is the extra compressibility, not extra durability.
