Sea to Summit eVent® Dry Compression Sack grey XL/30L

Compression without a purge valve — air escapes through the base, not a mechanical fitting.

The Sea to Summit eVent® Dry Compression Sack uses an air-permeable eVent® fabric base to push air out under compression while blocking water ingress. The body is 70D Polyurethane-coated Nylon rated to 10,000mm waterhead with double-stitched, fully tape-sealed seams. A non-wicking roll-top closure and four-strap lid deliver even, controlled compression across the load.
