These Srixon ZX MKII Hybrids come with all-new technology in the form of Rebound Frame’s dual flex zones to create purer energy transfer to achieve phenomenal distances. The new shape has allowed Srixon designers to place the mass deeper into the clubhead. Built on the input of Srixon’s professional staff, the all-new ZX MKII Hybrids have an appealing look, neutral face angle & squared-off toe.
