Port Co Adult Male Men Plain Short Sleeves T-Shirt Olive Drab Grn 4X-Large

I typically wear a small except in some cotton tshirts such as Hanes. Considering this I ordered this tshirt in medium just in case. It fits better than Hanes medium, not as loose but still a bit looser than a small in other brands such as athletic works. Overall it's a very nice shirt; feels well made, comfortable fabric and best of all, the same color brown tshirt we wore in the army underneath our woodland bdu. I would recommend this, it's a good shirt. 5'9 137 lbs.
