Back for another run around the block, the Fuel Belt Helium H20 2 Bottle Hydration Belt is back with a leaner profile and the same ergonomic design. The belt is secured via hook and loop straps, which can be adjusted to fit just about any waistline. Breathable Hex Foam padding ensures a comfortable ride on those longer runs. The redesigned bottle holsters secure the included 7oz ergonomic bottles, and they are specifically shaped to eliminate bounce and provide easy access while you run. An attached storage pocket keeps your keys and phone handy when you're training in town, or can be removed when its race day.
