CamelBak M.U.L.E. Hydration Pack

There's a reason this is one of CamelBak's bestselling, longest-running packs: it's got 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 of mountain biking, it won't get in your way. Since they launched the first M.U.L.E. in 1996, mountain bikers have been telling us that it hits the sweet spot of size vs. storage: it's lightweight, but big enough to carry three liters of water and a day's worth of snacks and gear. Over the years, we've also added air channels to keep your back cool, plus clever compartments for stashing tools, keys and electronics.
