Because every move and every gram matter in the high mountains, this expedition backpack meets all the requirements of committed alpinism, with minimum weight plus a proven format. Even more lightweight and robust, its exclusive ROBIC DOTTED LINE™ fabric delivers strength and reliability. Compact load carry is ensured over time by the X-LIGHTER™ heat-molded foam back. With a clean-cut body that eases movement, and a raised hip belt for walking in deep snow, the PROLIGHTER 60+20 targets functional precision to let you save maximum energy during ascents. Ice axes, ropes, skis, apparel, bivy mat and sleeping bag - it manages the essentials and keeps your gear ideally secure.
