Grab the CamelBak M.U.L.E. Hydration Pack before you head out for an extended single-track ride. With enough water for at least three hours of back-breaking exertion, the three-liter reservoir and Big Bite valve make staying hydrated the least of your concerns. The insulated reservoir pocket keeps your H2O cool even on blistering summer days, and the removable sternum strap and waist belt let you dial in the perfect fit. Two storage pockets keep your pump, tube, patch kit, and energy bars organized, and the MP3 pocket sports waterproof zipper so you can jam to your tunes in just about any weather. Stash your jacket in the overflow storage, cinch down the two compression straps, and concentrate on the trail ahead.
