A versatile, durable, and beautiful carry-on travel backpack driven by a simple truth: no two trips are the same. Features top, side, front and rear access via intuitively placed weatherproof zips. 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. Tons of internal and external pockets, plus a main cavity that’s divisible via a zippered mesh sleeve. Tuck-away shoulder straps and hip belt use unique magnetic catches to stay magically in-place when checking your bag. 360-degree grab handles. Cleverly concealed external carry straps. All packed within a sleek, weatherproof 100% recycled 400D nylon canvas shell.
