Yonex POLYTOUR SPIN is a polyester monofilament with a pentagonal profile, developed for aggressive play in which ball rotation is a primary priority.
Its five-sided construction helps engage the ball on contact while delivering a solid, defined feel. Yonex targets players with fast, forceful swings who actively seek topspin from the baseline.
The 200 m reel has a 1.25 mm gauge (16L) in the official Black colourway. The reel format is suited to repeated racquet stringing in a workshop or club.
