The GoSports recreational Volleyball was designed to provide a great all-around Volleyball for recreational players. The Volleyball is official size and weight, can be used indoors or outdoors and has a soft touch surface to minimize sting on your hands and wrists. The soft touch surface is especially great for younger players because the sting from cheaper volleyballs is the #1 reason kids don't like playing Volleyball. The balls are constructed using 18 machine sewn panels with an inner butyl bladder. Butyl bladders are far superior to rubber bladders as they help maintain the balls roundness and also hold air much better. We also include a premium air pump with the ball so you can always ensure the ball is inflated to the proper pressure.
