I'm size XL and although they fit quite well, they feel a little short. The XL size makes them seem a little tight, but that doesn't bother me, it's mostly because of the length. It's not bad, but if you raise your arms all the way up you'll find some skin. The fabric is comfortable enough not to cause any discomfort. Solid colors are great. I have to complain that the printed part of the label comes off too easily. It's hard to tell which side is right if you can't see the label. All in all a good set of training t-shirts.
