Load up all the water and gear you need for a day of mountain biking with the Camelbak Mule NV Hydration Pack. A three liter Antidote Reservoir graces the hydration sleeve of this beauty, and it's loaded with features that make it easier to fill, easier to clean, and easier to live with. The NV back panel features articulated pods that deliver maximum comfort and superior airflow to keep you cool and comfy mile after mile. The Antidote reservoir includes a lightweight quick seal cap, folding arms on the port aid drying, and baffles in the body that allow the reservoir to maintain a lower profile when full. The Quick Link system in the reservoir allows you to quickly snap off the tube for cleaning and easily attach accessories like filters, flow meters, and insulated tubes. An Ample main compartment and multiple exterior pockets hold your rain gear, multi tool, pump, spare tube, lunch, MP3 player, phone, wallet, and keys, while XC Helmet Carry stows your dome protector. The waist belt with cargo pockets keeps the pack from bouncing around as you bomb downhill. HydroGuard antimicrobial technology inhibits bacterial growth on reservoir and tube surfaces, and the Ergo Hydrolock shut off valve allows you to control water flow and prevents leaks.
