There's a reason this is one of our bestselling, longest-running packs: it's got everything you need, and nothing you don't. The latest edition is built around the brand new Crux reservoir, which delivers 20% more water per sip, with an ergonomic handle for easier refilling, and an on/off lever that makes it easy to prevent leaks. The pack also features a Magnetic Tube Trap to keep your tube secure and accessible when you need it and reflective accents for visibility in low-light environments. Color: Black
