Carrying case-sized backpacks with a military feel can be carried on board.

CABINZERO, a British travel bag brand, was born from designer Neil Varden's travel experiences. It's attractive size is that it can be carried on most airlines, it's extremely lightweight, and it's highly durable. This backpack with a catchy daisy chain can hold 36 liters of luggage for 2-3 nights, and boasts the same storage capacity as a carry case. Even when it gets heavy, the thick shoulder harness and back pad reduce the strain on your shoulders and back. Like other models, it is made from materials with excellent strength and water repellency, and is equipped with a zipper that can be attached to a padlock, a system to prevent lost baggage, and an OKOBAN tag. The green color gives it a military feel.
