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 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. Simple, rugged and reliable – the epitome of durability, versatility, and dry compression.
