Perfect dry compression storage for everything from bikepacking to sea kayaking and beyond. Made from a bluesign-approved recycled 70D nylon waterproof main body fabric and a 70D eVent® waterproof but air-permeable base that allows you to push air out while still keeping your contents dry inside. This means there's no need for a purge valve, making the Evac Compression Dry Bags light and simple. Four compression straps make it easy to evenly compress soft items, while the hypalon non-wicking roll-top closure also keeps the water out. DWR finishes on both fabrics are C0 non-PFC.
