Callaway Golf Speed Regime 2 Blem Golf Balls

Here is a simple, game changing fact: The SR 2 has been designed to have the best aerodynamic performance for athletic swing speeds between 90mph and 105mph. So yes, if your swing speed falls in this range, we’re talking directly to you. Our HEX pattern is specifically engineered to reduce drag at high speeds and increase lift at low speeds with a long, stable, penetrating ball flight that holds its line in the wind. And that means more distance.
