U/Sil Compression Dry Sack

This is a magic Compression Dry Sack- not only can it squash your soft goods down to a third of their normal size, but the bottom panel is made from an air-permeable, waterproof fabric called eVent. As you compress the bag you can feel the air being pushed through the membrane, and yet water cannot get in. Ideal for down sleeping bags and other compressible clothing. This latest version from Sea to Summit is constructed from 30D Ultra-Sil Cordura for astonishing strength-to-weight ratio, 40% lighter than the old version.
