This is the second long sleeved Moosejaw t-shirt I've gotten and I adore them. They feel nicer than my toddler's pajamas. Super stretchy, super soft, and super cozy.I love the look of this blue. For a cotton shirt it is quite vibrant.My wife calls it my "sexy" shirt because the V shows off my chest and the silky, drape-like material hangs off every curve. I bought the extra large and I probably could have gotten along with a large. I usually wear extra large with long sleeved shirts. This fits and feels more like a t-shirt, for which I almost always order large. So, buy your t-shirt size.
