We developed the Zac Speed COMP hydration backpacks and CoreFlex harness over 2 years of testing and feedback from our top level Hard Enduro riders. Tim Coleman competed in Romaniacs, Sea to Sky, Wildwood and Erzberg with prototype versions to fine tune the fit and feel of what we have today…. The ultimate competition hydration backpack.
