Super-size me. Just like the Alpinisto 35, the Gregory Alpinisto 50 backpack is made for the unrelenting weekend adventurer. Chock full of great features to make your adventure comfortable, the Gregory Alpinisto 50 daypack has a padded waist belt, Wraptor stabilizer system, HDPE frameset, foam bivy pad, hydration sleeve and port, full compression system, contoured top pocket for helmet clearance, and is leashless tool compatible. These awesome features combine to render the Alpinisto 50 a completely customizable climbing pack; allowing you to fully remove the waist belt padding, bivy pad and the HDPE frameset. This reduces the weight you’re carrying by one full pound, which goes along way when you need to change up from load bearing to lightweight summit mode. This pack has what it takes in varying degrees. It comes in three sizes (sm, md, lg) to suit your individual needs, and in Arnica yellow you can’t be missed. The Alpinisto 50 is for the serious minded adventurer.
