Sea to Summit eVent Dry Compression Sacks



Sea to Summit were the first company to introduce a compression dry sack to the market which does not use a purge valve.

This innovation uses air permeable eVent® fabric on the base, which allows air to be pushed out of the sack, while stopping water getting in. This is a lighter, simpler and more reliable solution than a purge valve. The body is made of a tough 70D Polyurethane-coated fabric. It has a non-wicking roll-top closure like the rest of our dry sack range and a lid with four straps for even compression.

Keep your gear dry and compressed as small as possible inside your pack, watercraft, or anywhere space is an issue.

    We have been using these dry sacks for a number of years with great success. They compress easily and we have used with confidence in a backpacks in all weather. We prefer the heavier 70D Fabric for durability.
