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.

Peak Design Travel 45 Review

Peak Design Travel Backpack - Moosejaw

A rugged, expandable, and beautiful carry-on travel backpack whose design is driven by a simple truth: no two trips are the same. The larger 45L bag is designed for longer trips and 1-bag-travel, the smaller 30L ideal for weekend jaunts and day bag use. On both sizes, you get big beautiful rear access via a #8 Ultra Zip, which can withstand decades of use thanks to its unique abrasion-resistant thread.
