An upgraded version of GoLite’s Jam Pack, the Jam2 is now available in men’s and women’s versions and has increased capacity. An ultra-light, multi-day pack, the Jam2 is designed for light and ultra-light backpacking, fastpacking, alpinism, winter day trips, rock and ice climbing, and summit bids. It features a roomy front pocket with watertight zipper, foam back pad, 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 Jam2 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.
