SpaceX Dragon polo black with logo on chest sz XL

This shirt is very cool. By SpaceX for SpaceX with Dragon logo on chest, the neck binding says SpaceX even the buttons say SpaceX. Unfortunately, the sizing does not show. I don’t know whether the facility uses some sort of technology like black light to show sizing, but I’ve usedinfrared to show the inside but I cannot make out the size. My husband is wearing it and he is a man’s large and it is just a touch too big in the shoulders so I would call it an extra large. Excellent condition, no flaws.
