Add personality to any look with the stretch-fit Genuine Trademark 39THIRTY Cap. We love the dimensional embroidery on this men's baseball cap – the bright orange 1903 on back. It's a great kick of color when the rest of your gear is black. • Materials: 97% cotton, 3% spandex. • Design Details: Official 39THIRTY silhouette by New Era. Contrasting stitching on bill. • Graphics: Dimensional embroidered graphics on front and back. Embroidered New Era flag logo on side. • Closure: Stretch fit.
