This sweatshirt is marked as a size medium, so I’m assuming it’s a boy’s as it feels too small for a men’s medium. It definitely can be unisex as well. Please check the listed measurements carefully to ensure a proper fit. This is in GUC with tons of wear left in it. It is long sleeved with a Classic crew neck in a nice navy blue. See pics for lettering and logos on this piece. Approx measurements: 18 3/4” armpit to armpit 23 1/2” sleeve length from shoulder seam 25” total length
