• Outer Structural Layer - This layer of construction gives the ball its final shape, playability, and durability attributes. Layers of cloth lining are laminated with high rebound latex compound which is then cured in a spherical mold to make each ball perfectly round and extremely durable.
• Latex Power Lining - This latex membrane is unique to Wilson volleyballs and provides maximum speed after contact. This layer provides a trampoline effect upon contact so the ball explodes off player's hands.
• Inner Structural Layer - Attached directly to the bladder, this inner layer of lining is the foundation of the ball. After the lining is attached, this unit is cured in a spherical mold for perfect shape.
• Butyl Rubber Bladder - All of Wilson's bladders are put through rigorous quality control checkpoints during the manufacturing process to ensure there are no leaks in the bladder walls or valves.
