    Carry of lots of gear in a simple design.

    Bring the ruckus on your next weekend-long backpacking excursion with the Mountainsmith Mayhem 45 Backpack. Crafted from the insanely durable multi-ripstop Cordura fabric, and with a giant asymmetrical zipper opening, the Mayhem is ideal for everything from gear-intensive day trips to short backpacking escapes. A spring steel frame, PE framesheet, and Anvil Airway EVA support construction delivers a fit and feel that's equal parts comfort and stability, which is only furthered by the adjustable waist belt. This waist belt also allows you to safely stash a smartphone in the built-in pocket. A bevy of pockets ensures you're never short on the gear you need most through your adventure, and generous tool and trekking pole attachment points keep your bigger items close at hand when you need to scramble with your hands free.

    • Familiarity: I've put it through the wringer

    I have a small frame so this bag's frame was a little too high for me. Coming up steep inclines proved dangerous as I'd have to lean out in order to see where I was going. Looking up was not an option, however that probably means better neck protection if I were to have fallen. This bag had ample room. I did not love the color nor the mesh on straps. I understand this is for wicking sweat however it snagged on most anything. Comfortable around the waist to wear not meant for a breasted woman on top with strap.

    Twice used great pack!

    • Familiarity: I've used it several times

    Used this pack twice so far a 5 mile hike in fishing spot and a full day trad climbing outing. Carried the loads great, plenty of room for a day pack, comfortable and great pockets! I don't hesitate at all to recommend this pack.
