For high and cold adventures with light but bulky loads, the Pinnacle is designed for all-season backpacking, alpine-style backpacking, mountaineering, and backcountry skiing. It features a large front pocket with watertight zipper, foam back pad and hip belt wings, cord lock to secure the top, top compression strap, two angled side mesh pockets, ice ax loops, two side compression straps, a haul loop, and 3-liter hydration compatibility. The Pinnacle uses GoLite’s ComPacktor system, which lets you reduce the pack’s volume through two fixed compression anchor clips that convert a multi-day pack into a day-tripper.
