Callaway Tour i(S) Golf Balls
Utilizing second generation Dual Core Technology, this ball produces maximum greenside spin on short iron shots while activating the inner core on drives to produce Tour-level distance with low spin. The soft Hyper-Urethane cover helps create even more wedge spin to feel and play softer than any other Tour-caliber ball Callaway has ever designed. HEX Aerodynamics reduces drag with 100% surface area coverage for stable, efficient ball flight in various weather conditions.
Callaway Tour i(Z) Golf Balls
With penetrating trajectories and fast ball speed this is Callaway’s longest Tour ball. It uses a Dual Core to achieve optimized performance for through-the-bag shot consistency. By activating a soft yet resilient inner core on drives, spin is reduced for longer shots while still delivering spin around the greens using the firmer outer core and soft urethane cover. The Tour i(z) also features refined HEX Aerodynamics for reduced drag and stable, efficient ball flight in all wind conditions.
Both Balls Feature Hex Aerodynamics
Similar to honeycomb covering a beehive, Callaway’s patented HEX Aerodynamics produce 100% surface area coverage on a golf ball whereas traditional round dimples typically cover only 88% of the surface. Dead space between dimples can cause inefficient flight characteristics so HEX geometries cover the entire ball to reduce drag and cut through the air with a strong, penetrating ball flight.
Featuring Spin Optimization
Dual Core construction produces “spin optimization” – the difference between high short game spin and low driver spin – crucial for optimum performance. Featured in Tour i Series balls, Dual Core technology uses two cores with different compressions in one ball so golfers can keep driver spin low while still producing short iron spin.
