This shirt definitely disappointed. All my work out shirts are cotton so I needed to upgrade especially since I am one to sweat. The reviews were overall good so I went for this one. But it did not deliver. Reviews claimed it was comfortable (reviewers even claimed to use this as lounge- and sleepwear) but it is not. At all. It is scratchy and rough and fibery. It's cut oddly so it has a strange shape, especially at the neckline and the rim. It has strings coming out of it. And to top it off, it's overpriced. Do not get this. Look elsewhere. I have not tried other UA products so these issues may or may not be restricted to this specific UA product but if I were looking to buy another work out shirt I would try a different brand.
