Both balls feature a Tri-Fast Core that gives the balls three layers of progressive compression. This allows the ball to flex [compress] and generate maximum energy transfer which is why this ball gives fast ball speeds. All of your club speed will transfer to the TP5 & TP5x balls.
The outer most two layers are why the balls will produce more spin around the greens. On the outside is an ultra-soft urethane cover which gives a soft feel, while the next layer is more rigid allowing it to “bite” into the grooves.
