Built to take a beating and keep gear dry, The Vault 65L Duffel Bag is a fully waterproof hauler designed for real use, not just airport runs. The 65-liter capacity is backed by waterproof materials and zippers, with a simple pocket layout to keep smaller items organized without overcomplicating things. An integrated air valve lets you compress bulkier gear like jackets and blankets to save space, and can double as a spout if you’re carrying liquids. It also converts from duffel to backpack with padded shoulder straps and a sternum strap, making it easier to carry when the load gets heavy. Tie-down points around the bag let you secure it to a truck bed, boat, or sled, so it stays put no matter how you’re getting there.
