Dunlop Hyperfibre+ Evolution Squash Racquets : The Dunlop Hyperfibre+ Evolution squash racquet is focused on power, speed and overall performance. The Hyperfibre+ technology features ballistic fibers built into this racquet at the 10 and 2 positions on the frame. These special technologies provide enhanced durability, stability, and ultimately better control. Increased stiffness and weight towards the top of the frame allows for even greater power on your shots. Built with a premium graphite construction. Endorsed by Dunlop Tour Team player Declan James. Aeroprofile features 9% smaller cross section in the hoop allowing for the beam to cut through the air faster and provide more elastic power.
