Tiny, compelling, and weighing as little as 57 grams for the XS size, it's the ultralight answer to keeping gear dry under sustained rain or wet brush. Built from 30D Ultra-Sil siliconized CORDURA fabric with no-seam construction for full waterproofing, it pulls over the pack in seconds, tightens down with the keeper strap across the harness, and packs into its own attached stuff sack so it can't get lost in the bottom of your pack.
