Hyper-G in short
Since 2014, Hyper-G has endured as the top string choice for tennis players around the globe. Developed for an ATP top 50 player, this shaped co-poly with an impressive combination of spin and precision allows big hitters to take massive cuts at the ball without having to worry about overhitting. The square profile with sharp edges bites the ball at contact, generating massive spin. Topspin players who like hitting balls that dive sharply and explode off the court should love this string. With an unmatched selection of 7 gauges from 15L to 20, there's a Hyper-G for every playing style.
V-Square in short
Volkl V-Square holds the top score for bite (string-on-ball friction) in the Tennis Warehouse University String Lab. The 4-sided square profile with razor-sharp edges creates vicious snapback and maximum spin potential. Made with an exclusive material for improved comfort with minimal tension loss, V-Square sits between Cyclone and Cyclone Tour in terms of overall feel while offering perhaps the best spin potential in the Volkl lineup.
