This durable, versatile, and impressively accessible carry-on travel backpack is designed with a fundamental principle in mind – no two trips are the same. Now available in Peak Design's exclusive Coyote X-Pac™ Ocean Edition fabric, made in the USA from 100% recycled fishing nets. It features top, side, front, and rear access through weatherproof #8 and #10 UltraZips, which use a proprietary abrasion-resistant thread and can withstand years of use. Meets international carry-on size requirements, but can expand to 45L for hauling gear or collapse to a 35L day bag, making it ideal for 1-bag travel. Plus, it has quick-access pockets for essentials like keys and passport, expandable side pockets for water bottles and tripods, and padded laptop and tablet sleeves. The main compartment can be divided into two sections with a zippered mesh sleeve, and there are tuck-away shoulder straps and hip belt, 360-degree grab handles. Cleverly concealed external carry straps. All packed within a sleek, weatherproof 100% recycled 400D nylon canvas shell with 900D bottom liner. Fair Trade Certified and 100% carbon neutral.

Compatible with Peak Design Packing Cubes, Camera Cubes and peak pouches (sold separately). For similar features in a smaller bag, check out the 30L Travel Backpack.
