When it comes time for serious training, throw on Camelbak's Ultra LR Run Vest before you head out the door. For supreme stability and bounce-free running, water is stored around the waist. Plus, it weighs only 1.15 lbs. and it has enough room to store a jacket and other essentials. In front, wide, adjustable shoulder straps help the Ultra LR fit snugly so it stays in place. These straps also have easily-accessible pockets so you can grab food on the fly. And, CamelBak's awesome 70-oz Antidote reservoir is included.
