The Dunlop Sonic Core Evolution 120 squash racket double pack features two frames made for superior stability provided with a hybrid-style shape, and to ensure supreme power behind each stroke without losing control. The racquet is endorsed by Nick Matthew and designed to provide added comfort and much smoother playability with the Sonic Core made with Infinergy by BASF lead technology which improves vibration dampening and grants extra stability. The racquet moves swiftly and gracefully through the air thanks to the head light balance, plus the first touch and control are enhanced due to the Flex Touch Resin. Both frames featured in the bundle are pre-strung with the Iconic pro AF (1.25mm gauge) string.
