Gregory's Alpinisto 35 Backpack is highly technical for climbers, alpinists, and ski mountaineers. Its Fusion Flex suspension system allows you to remove the top lid, supportive aluminum frame stay, stable HDPE frame sheet, and cushy padding to reduce weight for speedy ascents. Or you can keep all these suspension features intact for a highly supportive, stable, and comfy carry up into the alpine. The Alpinisto has a traditional top loading design, and Gregory added a side zipper for easy access to the main compartment. There are slots, straps, and pockets for skis, climbing ropes, ice axes, crampons, ice clippers, and more climbing gear. This backpack also has a hydration sleeve as well as a locking zip hose port. Side compression straps secure your gear for a stable ride to faraway places.
