The Gregory Alpinisto 20 L Backpack is a summit pack for snow-centric adventures on the mountain. Lightweight and durable, this all-weather pack holds the necessary gear and hugs the back comfortably. The CloudControl hipbelt offers soft support, the modular attachment straps hang onto gear externally, and an internal sleeve holds a hydration reservoir (sold separately). Attach your ice axes and take on the distance between approach and summit.
