There’s a reason this is one of CamelBak’s bestselling packs! It’s got everything you need and nothing you don’t. The M.U.L.E. strikes that perfect balance between size and storage with it’s 3-liter water reservoir and space to put a day’s worth of snacks and gear. This pack’s narrow-gauge design keeps it light and maneuverable, so even when it’s fully loaded for a day of mountain biking or adventuring, it won’t get in your way.
