Typical UA compression fit
I normally wear an S in tops, but with UA I like the Large size, for compression gear. Knowing that I ordered the large and it fits perfectly in the shoulders/chest. It's a bit wide in the hips, but I don't mind that since it's a base layer for me and works well at wicking moisture. The zipper sticks on the fabric on the inside, this is a pain, but it's still serving it's purpose for me, I ride my horse is very cold temps, get sweaty and after the ride, if I'm wet and cold, it's miserable, this top really helps with that issue.
