M.U.L.E.™ 100oz Hydration Pack


Since we launched the first version of this hydration pack 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 litres of water and a day’s worth of snacks and gear. Since then, we've taken that feedback and continually improved upon this, whilst adapting it to the future of the environment. This is one of our repurpose products which are made with sustainable materials in an effort to create solutions for a more sustainable life. The M.U.L.E.® has a narrow-gauge design that keeps it light and manoeuvrable—so even when it’s fully loaded for a day of mountain biking it won’t get in your way, and over the years we’ve also added air channels to keep your back cool, universal helmet hooks and clever compartments for stashing valuables. This latest version also features a magnetic tube trap that snaps easily into place so that you can hydrate easily without taking your eyes off the trail. There’s a reason this is one of our bestselling, longest-running packs: it’s got everything you need, and nothing you don’t.
