This is a YONEX T-shirt. I purchased it new and only tried it on. I am selling it because the size didn't fit and because it's see-through when worn alone. I welcome purchases from those who often wear an undershirt and understand the drawback of the see-through material m(__)m Product Information: Color: Shine Yellow Size: O Material: 100% Polyester Made in Japan ◎UV Cut ◎Absorbent and Quick-Drying ◎Anti-Static ◎Very Cool #YONEX #Yonex #Tshirt
