Small striking surface helps develop timing and sharpen accuracy and speed. Curved design provides anatomically correct positioning of the hand with a foam half circle on inside to secure the hand and add comfort. It's lightweight and easy to take on and off since there is no strapping system. Made of 100% leather. Multiple layers of foam provide support and an interior ball in the palm ensures that there is little movement on your hand while striking. Durable leather outer shell. Leather "hood" over coaches fingers gives hand protection from accidental strikes.
