Upgraded with innovative Auxetic 2.0 technology for enhanced stability and connection to the ball, the EXTREME JR tennis racquet lets up-and-coming juniors generate extreme spin and create chaos. Lighter and easier to handle than the adult racquets in the EXTREME series-which is endorsed by Matteo Berrettini-this offers a perfect combination of spin and power. The dynamic 16/19 string pattern helps juniors to produce even more spin while the design is daring and modern.
