Built to meet the demands of serious climbers, alpinists, and mountaineers, the Mammut Trion Zip 28 Backpack is a modern alpine pack that offers all the features needed to help you reach the top. Rope and ice axe storage options keep you ready for big wall climbs and icy summits alike, and a sturdy suspension system manages even your heaviest loads. The aluminum Motion V-Frame allows for comfortable, stable carrying even on your most gear-intensive missions. EVA padding on the back, shoulders, and hip belt provide lightweight cushioning, and the hip belt detaches so you can leave it at home when you're trying to shave weight. The hip belt is also narrow so it doesn't interfere with your climbing harness. Compression straps cinch down your load for better stability, and a large zippered flap opening offers easy access to your gear.
