CamelBak Circuit

Going for a run? Camelbak's Circuit Run Vest carries what you need. It weighs less than a pound so barely notice it, except when you need to drink. The wide, adjustable shoulder straps help the Circuit fit snugly so it stays in place. These straps also boast easily-accessible pockets so you can grab fuel on the fly. And, CamelBak's awesome 50 ounce Antidote reservoir is included for hands-free hydration.
