Versatile and high-performance, the Challenger 28 backpack is perfect for climbing, mountaineering, and ski mountaineering in extreme conditions. Made from Challenge Sailcloth Ultra, a lightweight yet highly tear- and abrasion-resistant fabric, it has a roll-top design that allows you to expand the capacity from 28 to 32 liters. Thanks to two practical compartments accessed via water-repellent zippers and numerous removable straps and cords for attaching rope, skis, ice axes, and helmet, you can customize the fit to your needs. Additionally, the back panel has a removable structured insert for greater support with heavy loads, the shoulder straps are fully adjustable, and the hip belt features removable padding for better load distribution and all-day comfort.
