The Allpa Travel Pack is a rugged, 35-liter backpack system built for adventure travel. This pack is perfectly sized for carry-on convenience, loaded with well-designed features, and tough enough to handle years of use. We started with a blend of tough, TPU-coated 1000D polyester, with durable 840D ballistic nylon paneling. We then adopted the low-profile harness we use for our backpacking packs to create a suspension system that distributes weight and keeps you comfortable through journeys near or far. The system includes contoured shoulder straps for comfort and balance, a padded hip belt to support the load, a breathable, airmesh back panel, and an adjustable sternum strap. There’s a suitcase-style, full-wrap zipper opening on the main compartment that opens into a large, zippered mesh compartment on the right side and a subdivided zippered mesh compartment on the left. Two zippered pockets round out the top. Padded laptop and tablet sleeves are accessible via the exterior right-side zipper. On the left side, there’s a shortcut zipper that provides access to the main internal compartment, without having to take the pack off your back. A subdivided compartment on the top is designed with passports and other small essentials in mind. As a security measure, all external zippers feature our theft-proof webbing sewn across the openings. A slotted back panel houses the shoulder straps and hip belt, ensuring loose ends are a non-issue in overhead bins, on the bus, or in the trunk of cars. Additionally, four reinforced grab handles provide multiple carry points when the shoulder straps are tucked away. There’s even a high-visibility rain cover that stows into the pack.
