A rugged, expandable, and brilliantly accessible carry-on travel backpack driven by a simple truth: no two trips are the same. Features top, side, front and rear access via weatherproof #8 and #10 UltraZips, which can withstand decades of use thanks to their proprietary abrasion-resistant thread. Meets international carry-on size requirements, but expands to be a 45L gear-hauler and collapses to be a 35L day bag, making it unmatched for 1-bag travel. Quick-access pockets for keys, glasses, passport, etc. Hugely expandable side pockets for water bottles, tripods, and more. Padded laptop + tablet sleeves. Main cavity is divisible into 2 compartments via a zippered mesh sleeve. 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.

Works seamlessly with Peak Design Packing Cubes, Camera Cubes, and Pouches, sold separately. For similar features in a smaller bag, check out the 30L Travel Backpack.

ONE BAG TO RULE THEM ALL

The 45L Travel Backpack debuted at the Outdoor Retailer show in 2018 and promptly won three best-in-show awards. Why? Perhaps because it was designed to do everything for everyone. 2-week journey? Check. Weekend jaunt? Check. Daypack? Check. Camera bag? Check. No two trips are the same, so get a bag with the versatility to do them all.
