$134

Lightweight, comfortable wraparound design and ergofit harness for improved stability and comfort.

The new MaxO2 foam adjustable closure system can be secured to match the pack's load. This innovative system allows the pack to conform to the body in one-touch and, like the MaxO2 Sternum, secures the pack in place without interfering with natural breathing. Eight pockets for access during action and durable ripstop fiber reinforcement at stress points. 3 sizes available.

ErgoFit.
The human body is a very complex and functional creation. Biomechanics have been incorporated into the design of our packs to allow for precise movement, load distribution, and never impede the movement of the human body.

Shoulder straps
The human shoulder is not straight. Shoulder straps on our packs are likewise not straight enough for a proper fit. Our pack straps are designed to follow the natural curves of the body over the shoulders and around the neck. Harnesses fit along the S-curve around the arms and chest without interfering with running motion.

Weight distribution
The harness construction allows the pack to balance the weight of the pack regardless of the pack's capacity, providing the best fit at all times. The load is placed low on the back, close to the hips, the body's center of gravity, and this placement helps to reduce unnecessary energy expenditure during long distance running, thereby improving the efficiency of running economics.
