This is my 4th t-shirt from MyProtein... The first 3 were great and fit perfectly, however slightly disappointed with this one. Overall the fit feels slightly looser, including the sleeves, and the material seems slightly thicker and just doesn't seem to fit as well against the body. This is despite all 4 shirts being the same size, and described as regular fit 100% cotton. Either the manufacturing process changed for the worse, or they have different shape style templates, and have failed to describe/distinguish them properly.
