When you're spending time in the mountains, either alpine hut to hut tours or multiple day routes, you need the Lowe Alpine Mountain Attack 35:45 Backpack with its technical design for an all around mountaineering backpack. An advanced WebCatcher system easily fastens axes, skis, and poles safely and securely, and the Adaptive Fit harness system gives you the perfect fit for your body every time. The hip belt is removable if you prefer to climb without one, and the top of the pack has an extendable and removable lid that is designed to make it easier to look up when wearing a helmet. All interactive points on the Mountain Attack 35:45 Backpack are easy to operate with gloves or mitts, including the advanced Headlocker ice tool attachment system. Engineered with an advanced Trishield nylon ripstop fabric, a silicone treatment in the coating of the backpack increases tear resistance by 20 percent.
