Details: VOL Technology: Utilizing multiple aerodynamic attributes including a new panel configuration, the ball adjusts to every player's style of play. Strike with confidence, pass with precision and get a touch that you can't find anywhere else. Panel Configuration: The ideal ball would have no seams, but that's impossible to produce with good surface quality. The new panel configuration accomplishes the next best thing, reducing the linear seam length. A seamless thermal-bonded surface repels water and mud to create consistency in any condition no matter what mother nature has in store. The thermally fused polyurethane cover material is paired with an elastic foam backing to retain shape and maintain softness for injury prevention and striking. A specially engineered high-rebound TPU bladder provides maximum air retention and durability so the ball retains its shape and you won't have to reinflate as often.
