Navy undershirt with raglan sleeves and excellent breathability. - Brand: Under Armour - Color: Navy - Size: M - Style: Undershirt Thank you for viewing. This was a gift, but I'm selling it because I don't use it. I think it's probably equivalent to a men's M, but there's no marking, so I'm not sure. Please check the size in the photos. It's generally stretchy. The underarms and back are mesh fabric and slightly see-through. There are a few snags in photos 14 and 15. Thank you. Gender...Men's
