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 non-PFAS DWR, and an Evac fabric air permeable base with a non-PFAS 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.
