Yonex Rexis Activate White 12m String

Yonex Rexis Activate 12m, a powerful and arm-friendly multifilament

The Yonex Rexis Activate is a 1.25 mm (16L) nylon multifilament that Yonex places in its power category. Its construction minimises the gaps between fibres to return more energy at impact.

It pairs that output with a soft, connected feel and a clean response, without the stiffness of a monofilament. The 12 m set strings one racket.

Which player is it for?

Yonex designs it for all swing speeds. It particularly suits players looking for easy power and comfort, and those who want to spare their arm by moving away from a stiffer string.

The Extreme Tennis team's verdict

The Rexis Activate ticks the boxes of a good club multifilament: it helps add depth without forcing and stays pleasant over time. Its Plasma bonding treatment aims to reinforce durability, often a weak point for this kind of string. Torn between this and another multifilament?
