The Blue Camelbak M.u.l.e.® 100 Oz Hydration Pack has everything you need, and nothing you don’t. The M.U.L.E.® has a narrow-gauge design that keeps it light and maneuverable- so even when it’s fully loaded for a day outdoors. The latest edition is built around the brand new Crux reservoir, which is even easier to load and re-fill, and delivers more water with every sip. It’s lightweight, but big enough to carry three liters of water and then some. It also sports breathable air channels to keep your back cool, universal helmet hooks, and clever compartments for stashing tools, keys and smartphones. The latest version also features Magnetic Tube Trap™ that snaps easily into place, so you can hydrate without taking your eyes off the trail.
