More capacity, same mission. The Vault 100L Duffel Bag stretches the original design into a longer, higher-volume hauler built for bulkier loads, with added hip straps to help manage the weight when it’s fully packed. It keeps the core features intact—waterproof construction, a sealed exterior pocket, and internal retention straps to keep gear from shifting—while the air valve lets you compress soft items to free up space or carry liquids when needed. Sized for bigger trips and messier gear, it handles everything from wet kits to dirty returns without leaking into your vehicle, then straps down securely when it’s time to move.
