YONEX white size S badminton wear, made with breathable VeryCOOL Dry material. - Brand: YONEX - Size: S (JP) - Design: White/Gray stripe - Material: VeryCOOL Dry Thank you for viewing. This game shirt can be used in official matches. The back and side lines are made of mesh material, which is cool. I am selling it because it no longer fits. I don't think there are any noticeable stains, but there is one small snag. It doesn't bother me much.
