All DERBYSTAR APS and TT footballs have been made from PU-materials and are therefore guaranteed PVC-free. Compared to PVC-balls, they are softer and can be played more accurately, with a more stable ball movement through the air and on the ground, including bouncing.
These features are also maintained at lower temperatures, where PVC-balls tend to become harder and loose performance.
Finally the PU-ball has a substantially longer life than a PVC-ball.
