Overview
Every mother has a favorite child and ours is the Circuit. Weighing in at just over two pounds, we don't think there's a pack out there that can compare to the load carrying capabilities, comfort, and durability of the Circuit. If you have your total pack weight down around thirty pounds and want to travel light, this is the pack for you.
