For those searching for superior hydration in a practical mountain biking backpack, CamelBak provides an exceptional solution. The CamelBak M.U.L.E. Mountain Biking Hydration Pack is the perfect biking backpack to add to your mountain biking equipment list. It features a narrow-gauge design that keeps it lightweight and exceptionally maneuverable. Even when this lightweight backpack is fully loaded for mountain biking, it won’t get in your way. Our M.U.L.E. hydration pack is built around a revolutionary Crux reservoir, which is easier to load and refill and delivers 20% more water with every sip. It also includes a self-sealing bite valve and an ergonomic cap. We’ve also added a Magnetic Tube Trap that keeps the tube secure and accessible when you need it. There’s a reason this is one of our bestselling, longest-running packs: It’s got everything you need and nothing you don’t. Our backpack is lightweight but big enough to carry three liters of water and a day’s worth of snacks and gear. It also contains five easy to access storage pockets that provide plenty of space to stash your tools, keys, and electronics. We’ve also added additional air channels to keep your back cool, universal helmet hooks, and a removable stability belt. Our biking backpack is designed with reflective accents to improve visibility during low-light situations, which improves safety while you’re on the road. It also features a magnetic tube trap that snaps easily into place so you can hydrate without taking your eyes off the trail. Our Got Your Bak Lifetime Guarantee covers all reservoirs, backpacks, bottles, and accessories from manufacturing defects in materials and workmanship for the lifetime of the product. The CamelBak M.U.L.E. hydration backpack only weighs 1.37 pounds and measures 17.9 x 8.7 x 8.9 inches.
