eVent™ fabric is an air-permeable, waterproof laminate used in two different functional areas in Sea to Summit products:
In the base of our best-selling eVent Compression Dry Sacks, Evac Dry Sacks and Ultra-Sil™ Compression Dry Sacks. In this application, the laminate utilizes a 40 denier nylon face fabric: the material allows air to be pushed out of the dry sack/compression dry sack but prevents water from entering. This means you can compress the air out of a dry sack without needing a purge valve!.
In the upper section of our Quagmire and Alpine Gaiters. In this application, the laminate utilizes a 70 denier nylon face fabric. The material allows perspiration to pass through easily but prevents external water from entering. The result: waterproof protection and superior breathability!
