100% cotton custom slim fit polo shirt, offering a comfortable feel. - Brand: POLO RALPH LAUREN - Fit: CUSTOM SLIM FIT - Material: 100% Cotton - Country of Manufacture: Vietnam Thank you for viewing. Although the size selection only went up to 160, the tag says 170. I've worn it for several seasons and washed it many times. There is some blackening, wear, and stains that won't come out. Also, I didn't notice it until now, but there's a hole under the left sleeve. #PoloRalphLauren #170 #PoloShirt
