The eVac™ Dry Sack utilizes 70D lightweight nylon fabric for strength and eVent® waterproof fabric on the base to allow eVac-uation of air for compression. It's an excellent option for storing and compressing clothes and sleeping bags without the use of straps. Just pack the items in, roll the sack down and push the air out to save valuable packing space within your backpack. They're an oval shape, making them perfect for sliding into the contours of your pack and all seams are double stitched and tape-sealed.
70D Waterproof Fabric - High Performance
Super tough, super pliable, high thread-count 70 Denier fabrics. The PU coating is highly waterproof (rated to 10,000mm hydrostatic head), and is colored bright white to make it easy to find your gear inside these bags.
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!
