Designed for technical mountain pursuits, the Challenger 28 Backpack delivers versatile performance for demanding alpinists.

The versatile Challenger 28 Backpack is a go-to carry-all for mountaineering, alpine climbing and ski mountaineering. Made from rugged, tear-resistant Challenge Sailcloth Ultra fabric, this durable, lightweight pack is built to withstand ice, rock and harsh conditions. The practical roll-top tubular construction can increase capacity from 28 to 32 litres for more gear-intensive missions. A drawstring closure divides the main compartment into two sections for easy organisation, with both sides accessible via water-repellent zippers. And various removable external straps and cords allow you to transport ropes, skis, ice axes and helmets, so you can customise your setup whether you’re scaling icy walls or descending on fresh powder. The back panel comes with a structured, removable insert for extra support with heavier loads. Fully adjustable shoulder straps and a waist belt with detachable hip pads ensure optimal weight distribution for all-day comfort. For ambitious alpine adventures, choose the Challenger 28 Backpack.
