ZX5 MKII combines enhanced forgiveness, exceptional feel and a sleek look to give you straight, long and high drives that go the distance. The Rebound Frame returns with Dual Flex Zones that channel more energy into the ball at impact for higher ball speeds and longer distance. For increased structural integrity, the Star Frame Crown features extremely thin titanium that places mass where its needed for ideal launch and spin. An intricate Variable Thickness Face pattern creates a larger, high COR area across the entire face to produce more energy from the swing into the ball on off-center strikes.
