Tecnifibre DNAMX Squash String is a power string with the focus on high elasticity of the string to catapult the ball away. It has the traditional PU outer to give the unique playability of Tecnifibre string. PU HDX Inside used as the outer for this string is highly elasticated to give maximum repulsion and bounce for the ball. Elastyl fibres in the core have high stretch and recovery to give rapid acceleration to the ball. SPL2 on the outside of the string lubricates the string to string contact for less wear.
