The Camelbak Ambush 3L Mil Spec Crux is perfect for shorter missions. It optimizes the area on a user's back with a wider platform, shorter torso length, and reduced stack height. The external access to the 3L Mil Spec Crux Reservoir provides 25% more water per sip. This hydration pack includes external fill, making it easy to refill without removing the reservoir from the pack. It features 500D Double-rip Cordura fabric for strength and durability, top and bottom external zip pockets for storing essentials, and a low-profile Mountain MOLLE on the bottom pocket. The side-release shoulder straps allow for rapid removal, and the side zippers provide easy access to the reservoir fill port. The pack also includes D-Rings for tube management, a lightweight webbing harness, an adjustable sternum strap, and a hook-and-loop strap management system. The ergonomic webbing grab handle makes it easy to carry, and the drain hole on the hydration compartment helps to prevent water from accumulating.
