From all-day hikes to multi-day backpacking missions, any time we are on a trail, we trust the Hyperlite Mountain Gear Unbound 40L Backpack. Sporting Hyperlite's now-legendary DCH fabric, this backpack maintains a light weight despite its impressive durability and ample carrying space. The single-stay harness centers the 40-liter load on our back, while multiple external pockets keep important items within arm's reach at all times. Small details, like an internal trash pocket and gear loops, provide constantly impressive versatility.
