This double pack is made up of two Head Graphene XT Xenon 135 Slimbody squash rackets. The Xenon 135 uses Graphene XT technology to increase your swing speed & power potential by incorporating the lightest material in the world & optimising the distribution of weight across the frame. This thin beam racquet is aerodynamic & evenly balanced, speeding up your swings & giving good feel. The 73.5in 2 (475cm 2) head is a fraction more compact & at 135g (4.8oz) the frame’s weight is quite low. Both rackets are strung with an Evolution Pro string in a 14x 17 pattern & each have a protective full cover included as well.
