The Maxfli Revolution EXT Distance has been engineered to deliver even more yardage than the Revolution EXT. It incorporates Maxfli's SpeedMantle Technology, a thin layer sandwiched between the cover and the core that increases the speed at which the ball leaves the clubface, making the EXT Distance both faster and longer. In addition, SpeedMantle technology helps to deliver a high launch angle and low spin-rate off the driver, optimizing distance, while at the same time providing soft feel with the short-irons for improved spin and control. The EXT Distance differs from the EXT due to its slightly firmer cover which is significantly faster; and its core which is lower in compression, and thereby softer-feeling. The fast cover works with Maxfli's SpeedMantle to deliver both low spin and extreme speed off the driver, resulting in maximum distance, while the softer core helps the EXT Distance to maintain a soft feel at impact.
