For sale is a used Uniqlo DRY-EX color block crew neck short-sleeve t-shirt athletic top in Blue (66), men's extra small (XS). I bought this shirt and used it occasionally, and it is in good used condition. There is slight wear and pilling when viewed up close as I tried to show in the pictures. The shirt is made of a light, breathable material with a light blue mesh on the bottom and a darker blue portion at the top with a pattern of small holes in strategic areas. See the photos for measurements; I generally wear a Small in most brands and find that these XS shirts fit like a slim-fit Nike Small.
