Theres a reason this is one of our bestselling longest-running packs: its got everything you need & nothing you dont. The M.U.L.E. has a narrow-gauge design that keeps it light & maneuverableso even when its fully loaded for a day of mountain biking it wont get in your way. Since we 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: its lightweight but big enough to carry three liters of water & a days worth of snacks & gear. Over the years weve also added air channels to keep your back cool plus clever compartments for stashing tools keys & electronics.
