Rexis Activate Set

The firmest feel in the Rexis family. Still plush enough to trust. The Yonex Rexis Activate is a premium multifilament tennis string engineered for enhanced playability across all swing speeds — giving comfort-seeking players the control to swing bigger and add pace and spin, without losing the plush, arm-friendly feel the Rexis family is known for. At the core of Rexis Activate is FRF (Fusion of Resin Filament) technology, which minimizes the natural gaps between individual fibers for improved energy return at contact. Plasma bonding reinforces the string's structure at a molecular level for enhanced durability, while FORTIMO elastic polyurethane — developed by Mitsui Chemicals — increases flexibility and repulsion, resulting in superior ball-pocketing and effortless power on every shot. Positioned as one of the firmest members of the Rexis lineup, Activate delivers above-average control compared to softer multifilaments — making it easier to commit to full swings and generate real pace and spin, while still protecting your arm through the natural shock-absorbing comfort multifilament construction provides. It's the ideal choice for players who want a connected, controlled response without sacrificing the plush touch that makes Rexis strings a favorite among comfort seekers and players managing arm sensitivity. Smooth. Consistent. Dialed in from the first serve to match point.
