This is my second shirt from this company. My first was the short sleeved version. This shirt has a more slim or contoured fit, which is super if you're perfectly lean. I checked out their sizing on their website and ordered accordingly. I typically wear a Large shirt, but due to the contoured fit of this shirt, I opted for the XL. I'm glad I did, because I believe the fit is more of a regular fit, and much better for me. A Large would be too tight especially after washing and drying. This time I wasn't really impressed with the weight and feel of the fabric. The fabric is soft and maybe a little on the thin to clingy side. I don't like how it shows a lot of chest detail including nipples, and even where your chest hair is located! My chest hair was even poking through the fabric at one point. I ordered the Pewter, but maybe a darker color wouldn't be so revealing. I'm really bothered by that. I mean are these shirts designed and made for men or what? Last time I checked, I'm not the only man with some hair on his chest. So I expect clothes that will work with my body. Overall I'm satisfied with the shirt, but I do think this company is a little pricey for the quality. I'd also recommend checking the size chart on their website. Order up if you don't want the contoured fit, and prefer a more regular fit. If you're a hairy guy, I guess get ready to wear another shirt underneath. Thumbs down for that.
