The Callaway Speed Regime 1 is designed for swing speeds of up to 90 mph.
Soft Feel with Tour-Level Control: Soft cover promotes Tour-level control on approach shots and shots around the green
Ultimate in Spin Separation Designed For Your Swing Speed: Soft inner core generates low spin off the driver for long distance
Firmer outer core generates higher spin rates for more spin and total control with aggressive stopping power on short irons and wedges
The thin inner and outer mantles produce more ball speed and reduce spin off the driver for maximum distance
