Perfect dry compression storage to keep gear reliably dry and compact inside a backpack or bike bag. Made from bluesign-approved ultra lightweight Ultra-Sil 30D Cordura nylon with a C0 non-PFC DWR, and an eVent fabric air permeable base with a C0 non-PFC DWR finish that allows you to push air out while still keeping your contents dry inside. This means no need for a purge valve, making the Evac Compression Dry Bag UL light and simple. Compression straps make it easy to evenly compress soft items, and the hypalon non-wicking roll-top closure also keeps the water out. Simple, extremely light and reliable- the perfect dry compression solution for internal use.
