The GoLite Pinnacle Pack carries 4500cu inches worth of gear at an incredibly low 1lb 9oz weight. This is a great pack for fast packers and alpinists who strive for simplicity in their gear. The Pinnacle Pack's lidless design helps it achieve its low weight and provides a clean profile. GoLite added a large front pocket to provide a place for smaller items like your extra pair of gloves. The foam back panel supports moderate loads and allows you to move freely as you hike or ski. The Pinnacle Pack also includes a hydration sleeve to hold your favorite 3-liter bladder and keep water accessible.
