Sea to Summit EVent Compression Dry Sack

We were the first company to introduce a compression dry sack without a purge valve. Air permeable e Vent fabric on the base allows air to be pushed out of the sack, while stopping water getting in: lighter, simpler and more reliable than a purge valve. The body is made of a tough 70D polyurethane coated Nylon. It has a non-wicking roll-top closure and a lid with four straps for even compression. Specifications. 10,000mm waterhead, rugged 70D Nylon body and lid. Double stitched and tape sealed seams. Non-wicking roll-top closure with lid. Bar tack reinforced stress points. White interior for better visibility of contents. Pull handle on the bottom. Includes Field Repair Buckle. Size: 8''x18''. Weight: 5.2 oz / 148g. Max/Min: 14L to 4.5L.
