Arc Air DCF 50L Backpack DISC rock sack I think it would provide**This backpack has been replaced by our newer Arc Haul Ultra. 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.
