Adjustable to fit most players with different waist sizes. The bungee cord gives you enough length to hit even overhead jumps and spike serves without the ball bouncing back into your face.Standardize Hand Movements: Use the adjustable strap with plastic button reinforcement to securely fasten to the palm to reinforce the correct position of the hand on the ball to standardize hand movements or reduce fouls to avoid touching the ball when adjusting during training.
