The Revenge Series is a break through in hydration belt design and function. One handed entry and exit has never been easier with unique and cleverly designed molded holsters. With just one hand, bottles go in fast and come out faster. The great news is that these holsters will work with all past and present FuelBelt bottles. The new design is super lightweight and available in a One Size Fits All. As if that's not enough, our new color ways come directly from some of the greatest endurance athletes of our time including Terenzo Bozzone, Craig Alexander and Chrissie Wellington.
