You will find that the large size works for travel, and the strap padding keeps you comfy.

I like how this Pacsafe backpack balances simple style with practical bits that help everything feel secure when you are out.

I like how the US Army brand ties it to real-world service and reliability.

With the Slumberjack badge in place, the backpack looks ready for real-life use.

The size is adjustable, so you will it fits under seats and in overhead bins.
