Yonex POLYTOUR FIRE is a polyester monofilament for players seeking greater pace and spin from a committed swing. It is aimed at medium to fast racquet-head speeds.
SIF (Silicone Infused Filament) technology incorporates silicone oil into the string. Lower friction between strings supports snapback and the responsive power and spin highlighted by Yonex.
The 200 m reel has a 1.20 mm gauge (17) in the official Red colourway. The reel format is suited to repeated racquet stringing in a workshop or club.
