A rugged, expandable, and brilliantly accessible carry-on travel backpack driven by a simple truth: No Two Trips 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.
