This is a long sleeved thermal shirt. I tried it on and I am in LOVE. I've been working on losing weight and this shirt was supposed to be my "goal shirt" because it's a large and I used to be a 2XL. The actual size is like anywhere else's medium (I compared it to my other medium shirts). So that means I've dropped even more than I thought! I'm so happy!
I did, however, order this shirt when it was still cold and it's just now getting to me. There was an error in their warehouse and so it took a little extra time, but after trying it on, I don't even care.
