Urethan
The material of the outer layer / cover of a premium golf ball.
Urethane is a soft polymer, which gives the player in contrast to the classic "Distance" balls with hard "Surlyn Cover " a much better feel and control over the ball, without sacrificing length and control.
However for shots under 150m and in the short game, the advantages of urethane balls are overwhelming.
We therefore believe that "Surlyn" balls are only the second best option...
