Mountainsmith Mayhem 45L Backpack, Heritage Black

The 2019 Mayhem 45 is an ultralight, ultra-durable, and ultra-comfortable backpack, built with Spectra Fiber, which offers a top-tier strength-to-weight ratio. Spectra Fiber, used by military and law enforcement, is an ultra-high-molecular-weight polyethylene known for its lightweight strength and abrasion resistance properties. This means more efficient pack carry, more mileage, and a lifetime of adventures with the Mayhem 45. Less pack weight also translates to more room for the essentials—like melted chocolate bars and squished PB&Js.

Designed for one to three night backpacking trips, backcountry huts, gear-heavy days at the crag, and adventure travel, the 45-liter Mayhem 45 features a hybrid top and panel opening for easy access to the front of the pack, a must-have for tight environments and organized packing. 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, providing a lightweight but intimate suspension fit and high levels of stability and comfort.

The Mayhem 45 offers ample storage options, including a large front zippered pocket with a document sleeve, an internal zippered mesh organization pocket, and pen slots. The layflat expanding stretch mesh side pockets can accommodate up to 24oz water bottles, and the rear dedicated zippered and padded compartment fits up to 16" devices. For quick access, the soft-lined zippered quick-stash pocket is perfect for a phone or sunglasses.

All Mountainsmith products are backed by the Forged for Life Guarantee, the official Mountainsmith lifetime warranty, ensuring the quality and durability of the Mayhem 45. With its exceptional strength, lightweight design, and versatile storage features, the Mayhem 45 is the ideal choice for your next backpacking, camping, or adventure travel excursion.
