Cons Designed for a specific use, relatively small capacityLarge capacity makes it less versatileA little small for a bear canisterRelatively heavy, delicate carbon frame rodsFoam pad falls out easily, shoulder straps lack support
Bottom Line This 40 liter pack is designed for light and fast missionsAs an all around great pack, it can carry large and light loads with ease, has plenty of external storage options, and is super comfortableOne of our top picks and scored highly in all metrics, it's comfortable, versatile, and has just enough featuresThis pack is a popular ultralight pack for good reason; it has plenty of outside storage, is made of durable fabrics, and carries both 15 and 30 pound loads with easeCombines simplicity, a reasonable price tag, and a good feature set
