100% cotton. Heavyweight loopback fabric. Ribbed crewneck with V-insert. Ribbed cuffs and hem. Regular fit. Jackmans Dotsume Owners Polo is not just your average Polo shirt, made from some PE-level pique and had a couple of buttons thrown at it. No, this beauty has been fashioned from some rather sumptuous heavyweight loopback fabric and treated to thick slabs placket-eering around the neck region. The grandiosity of that ribbing is a real sight to behold too.
