Thank you for viewing. My middle school son wore this only 2 or 3 times. Black high-neck undershirt, size M, made of 91% polyester. - Brand: diadora - Size: M - Material: 91% polyester, 9% polyurethane - Color: Black - Design: High neck Although it's size M, it might be a bit small due to the stretchy material. There is a name written on the back of the tag. There is a white stain on the lower abdomen. It did not come out in the wash. Please check the photos. Thank you for your consideration.
