Long-sleeved shirt with a high-neck design, size L, made of breathable polyester material. - Size: L - Material: 88% polyester, 12% polyurethane - Design: Long sleeves, high neck Thank you for viewing. This shirt belonged to my son when he was in upper elementary school and junior high school. He didn't like wearing undergarments, so he didn't wear this much, and it's in good condition. I don't think it's a sports item, but how about it for protection against the cold in the coming season?
