Evolution, the flagship rubber series from TIBHAR. Evolution offers two different categories of rubber types to get the most out of your specific playing style; -S and -P. The Evolution -s line employs a unique rubber mixture resulting in a softer topsheet. A rubber of this caliber allows for better feedback. This results in even more potential to produce spin on the ball, more feeling for exact placement, and more control and safety on all of your strokes. This helps you hit those winning balls that will take you to the next level! Evolution EL-S strikes more of a balance between MX-S and FX-S, though under close inspection, EL-S leans more on the side of MX-S. With just a little extra softness, this rubber gives you the dwell time needed to hit the perfect attacking stroke!
