SKLZ Impact Golf Balls are a regulation-sized training golf ball perfect for a variety of practice applications. Constructed with proprietary pop-back technology, Impact Golf Balls are indestructible and resistant to dents, lasting much longer than traditional plastic golf training balls. The limited-flight design also makes these balls ideal for practicing in small spaces, perfect from everyday home training sessions. The black and yellow design helps players track ball spin and path during putting, chipping, and driving practice. Each pack of Impact Golf Balls include 12 training balls in a mesh carrying bag and is covered by a one year warranty.
