I am extremely cold natured but during the summer a sweatshirt is a bit much but these shirts are perfect! They keep me extremely comfortable. I have put on weight due to medications and do not want anything clingy but dont want something from Omar the tent maker either, these shirts are a perfect fit, longer than a normal tee and really soft. For reference I am currently 180 pounds and 5'4, I got xxl and they are a perfect fit, not tight and not baggy. I have ordered 3 so far and am ordering more colors. They wash well and no shrinkage in the dryer. When I get off this medication and lose the weight I will use them for sleeping ( they are that soft!) or layering.
