Description

Mountainsmith Mayhem 45Why compromise when you don't have to? The 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 lightweight strength and abrasion resistance properties. In the Mayhem 45, this means more efficient pack carry, more mileage, and a lifetime of adventures.

Why compromise when you don't have to? The 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 lightweight 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 litres, 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 back panel 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 back panel allowing for a lightweight but intimate suspension fit and high levels of stability and comfort.

Excellent buy
Color: pink
I ordered this case for my new IPad. This case is awesome! Not flimsy and bulky. I loved that it had a screen saver included in the case. It was easy to put on my IPad. Snapped together good. The price was excellent! The case keeps all dust off the screen. The screen is easy to clean. I highly recommend this case!
