Sea to Summit Evac Compression Dry Bag

The base is made from an eVent fabric that allows air to be pushed out when you compress the bag, but its microscopic pores are too small for water molecules to penetrate. This lets you squeeze out excess air to save space without compromising the waterproof integrity of the bag.

It is fully waterproof. The bag features double-stitched, tape-sealed seams and a 2000mm hydrostatic head rating, meaning it can withstand significant water pressure. However, it is not designed to be submerged for long periods, so avoid using it as a flotation device or for underwater storage.

Place your soft gear inside, roll the top closure down at least three times, and then use your body weight or hands to press the air out through the base. Once the air is expelled, secure the buckle to maintain the compressed shape.

Yes. The bag is equipped with a field-repairable buckle, which allows you to replace it using only a small screwdriver or by sliding a new pin into place, ensuring you aren't stuck with a useless bag if the hardware fails while you're traveling.

The 30D Ultra-Sil nylon is designed to balance weight and durability. It is exceptionally light and strong for its class, but it is a thin fabric. It is perfect for internal organization inside a backpack, but you should avoid dragging it over sharp rocks or abrasive surfaces.
