Mountainsmith MAYHEM 45 Backpacking Pack (Heritage Black)

At 45 liters, the Mayhem 45 is designed for one- to three-night backpacking trips, backcountry huts trips, gear heavy days at the crag, and adventure travel. The hybrid top and panel opening offers easy access to the front of the pack, a must-have for tight environments and organized packing. Toss the Mayhem on your back and the hex-ridged EVA backpanel padding allows for omni-directional airflow while the sock-style shoulder strap construction prevents the straps from digging into your body. The Interfaced Waistbelt system is designed and patterned to flow into the backpanel allowing for a lightweight but intimate suspension fit and high levels of stability and comfort.
