The Nomatic Travel Pack 20L is our best-selling pack and built for one to three days trips or day-to-day excursions near home. Featuring durable, water-resistant materials and YKK zippers, this pack is built to last. Starting at 20L, the Travel Pack quickly expands up to 30 liters via a full 360-degree expansion zipper, giving you 50% more space when you need to pack more gear. Our patented strap system allows you to go from backpack to briefcase carry for times when you need to look more professional. The full perimeter zipper provides access to 22 pockets, all designed with a specific purpose—from RFID safe storage, a hidden pocket for valuables, and tech organization with cord pass throughs between all compartments to charge seamlessly on the go. Plus, a TSA-approved fold down laptop pocket makes check points a breeze. In other words, whatever you need to carry, this pack has a spot for it. The spacious main compartment also includes a zippered mesh wall that provides access to the luggage compartment, which once expanded gives you the perfect space for packing clothes and shoes. Final touches include our innovative magnetic water bottle pockets, that expand when you need them, and snap shut when not in use to maintain a sleek profile.
