Thank you for viewing! I'm selling this because I don't have a chance to wear it. This is a red and black YONEX jersey. It has the HEAT CAPSULE function, which stores heat using infrared rays, so it's warm. I think it will be useful for walking or running in the coming season. As shown in the photos, there is a black stain on the lower right part of the back. It's barely noticeable, but please refrain from purchasing if you are sensitive to used items, seek perfection, or are concerned about minor details. Instant purchase is OK without comment! Thank you. * It will be folded and compressed for shipping. - Brand: YONEX - Color: Red/Black - Function: HEAT CAPSULE #yonex #yonex #tennis #junior #softtennis #badminton #coldprotection #Msize #running #runningwear #walking #walkingwear #sportsgym #gym #muscle training #training #trainingwear #windbreaker
