Not paper thin like most T-Shirts
Color: Light Khaki, Size: X-Large
These Cooney tshirts are really nice. Feel like 100% cotton and keep their shape and color. Size true to fit. Good value for the money. Love the mock neck style. Bot a couple one in white and one in black. Then went back and ordered 6 more various colors. Like the all.
