Millet's Prolighter 38 10 Backpack boasts a versatile performance for mountaineering, from winter ski touring to summer alpine climbing. Designed for a flawless performance in the alpine, the Prolighter's X Lighter Back ensures freedom of movement from the ascent to the descent, and high density foam with ventilated channels keeps you comfy through it all. The Continuous shoulder straps work with the padded waist belt to give flexibility as well as cushy comfort, and you can remove the waist belt when it's time to haul the pack up routes. The Prolighter 30 sports traditional top loading access and has an expandable lid in case you need for room for gear. There's an additional compression strap up top that doubles as a rope holder when your pack is full. Millet also equipped this pack with an FPP Ergo ice axe holder, reinforced ski holders, and two zippered pockets at the lid for valuables. Side compression straps secure your load for a solid ski down or a fun climb up.
