The original narrow-gauge hydration pack for mountain biking, the CamelBak M.U.L.E. Hydration Pack features a 3 L Antidote reservoir and plenty of cargo space for a full day of riding.

• 3 L Antidote reservoir has a quick-snap cap for easy opening and closing, a low-profile fit for more stability, and a lighter fill port to cut weight
• Quick Link system allows the tube to be disconnected from the reservoir for easy filling
• Extra-large opening makes the reservoir easy to fill and clean; hidden folding arms lock out for faster drying
• XV back panel features lightweight multiple-layer EVA foam pods that provide superior cross-ventilation
• Independent Suspension harness distributes weight evenly to provide all-day comfort and stability
• 11 L of cargo space gives you plenty of room for an extra layer or two and your lunch, phone, wallet, and keys, in addition to your bike tools
• Bike tool pocket keeps your bike tools, pump, and spare tubes organized and easy to access
• Hooks for lashing your helmet to the outside of the pack
• Media pocket for carrying a camera, a phone, or an MP3 player
• Removable 3/4 in. (20 mm) waist belt provides added stability
