The Revenge Series is a break through in hydration belt design and function. One handed entry and exit has never been easier with our unique and cleverly designed molded holsters. With just one hand, our bottles go in fast and come out faster. The great news is that these holsters will work with all past and present FuelBelt bottles.

Carries 2 7oz bottles on our lightweight helium style belt. Worn by Chris McCormack 2010 Ironman World Champion. Available in S, M, L, XL.
