Mountainsmith Mayhem 45L Backpack - Heritage Black | Durable Hiking & Travel Backpack for Outdoor Adventures, Camping & Daily Commute

Why compromise when you don’t have to? The 2019 Mayhem 45 is ultralight, ultra-durable, and ultra-comfortable. Built with Spectra Fiber, the pack offers a top tier strength-to-weight ratio. Used by military and law enforcement, Spectra Fiber is an ultra-high-molecular-weight polyethylene known for its light weight strength and abrasion resistance properties. In the Mayhem 45, this means more efficient pack carry, more mileage, and a lifetime of adventures. Less pack weight also means more room for the essentials—like melted chocolate bars and squished PB&Js. 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. All Mountainsmith products come with the Forged for Life Guarantee, the official Mountainsmith lifetime warranty.
