So far I've only been able to try this shirt out. I'm normally an XL based on sizing charts and usually the shirts fit nice around the arms and shoulders and chest and are looser around the belly. This shirt was the same. But either I misjudged and I should've gotten a L, or I'm losing muscle. 😭 Shirt is a little looser than I'd like. But I'm gonna try and shrink it some in the dryer and see how that works. Otherwise these shirts are great quality and form fitting. And I love the graphics and the message you stand behind!
