A big, beautfiul rear hatch provides total access for easy packing and unpacking. An enlarged top pocket is subdivided with stretch and zip pockets for keys, glasses, passport, etc. The weatherproof #10 UltraZip can withstand decades of use thanks to its proprietary abrasion-resistant thread.

Tuck-away shoulder straps and optional hip belt accessory. 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.

For optimal photo gear carry, we recommend the larger 45L Travel Backpack. Comparing to the 45L? The 30L is better for: 1-bag-travel for trips 3 days and under, Day bag use (perfect for exploring, commuting, and working, in a new place, or in your hometown), and as your carry-on personal item: fits more easily under airline seats.
