**This backpack has been replaced by our newer . It has a similar design but is constructed with a more durable Ultra material.

From those grueling east coast ascents to long water carries across the desert, the Arc Air is a durable pack designed to be the ultimate combination of simplicity and function.

Featuring custom Curved Carbon Fiber Air Stays, the Arc Air creates a gap between your back and the pack for airflow and cushioning. The frame transfers weight to your hips, keeping the weight off of your shoulders and providing a comfortable fit.

Featuring adjustable shoulder straps, an interchangeable belt, and a variety of optional modular , the Arc Air is sure to become your pack of choice.
