CONCEPT : INNEGRA
"Innegra™ technology
The new hybrid composite structure HEAD Innegra ™ is integrated into the racket to absorb shock and improve stability. As a result, vibrations are reduced by up to 17% on ball impact for unique control and precision.
In addition to this, HEAD 's new hybrid composite structure with ultra-strong Innegra ™ fiber significantly improves the racket's long-lasting performance.
CONCEPT: POWERHOLES
The string rims on HEAD EXTERME 135 have been widened to let the strings breathe and encourage elasticity. The result is a softer string pattern and an enhanced soaking effect. A significant benefit in terms of power and forgiveness.
