A monster gear hauler, the Travel Duffelpack 65L maximizes your carry capacity without compromising comfort or versatility. Ergonomic padded backpack-style shoulder and waist straps support the heaviest of loads, yet stow instantly beneath magnetically-sealed back panels. Padded grab handles on all sides of the bag give quick carrying options. Integrated expansion zips offer a massive 20L of payload expansion (45 min to 65L max). A unique main opening features a burly #10 weatherproof zip and ultra-long zip path that gives you more access and visibility than traditional duffels. Internal volume is sized to perfectly fit Peak Design Packing Tools (sold separately) for customizable organization.
