Callaway Tour i(S) Golf Balls

ItÂ’s no secret that the groove rules instituted by the USGA are designed to reduce spin off wedges and short irons, placing more of a premium on shotmaking. The Tour i(s) leverages 2nd Generation Dual Core inertia technology, making it easier for golfers of all abilities to generate maximum short-game spin. The softest 4-piece Callaway Tour ball ever features refined HEX Aerodynamics for a stronger ball flight and more distance by reducing drag and promoting efficient ball flight in all wind conditions.
