I bought one of these muscle tee's from Champion a couple of years ago and was pleased with the quality - the cotton material was thick and durable. So when I needed some more muscle tee's, I decided to go with Champion again.

Unfortunately the quality has taken a dip. The cotton material is quite a bit thinner than it used to be. Also the neck hole is larger than before(I prefer the tighter fitting version) and the photos on Amazon is not representative of the shirt they are currently selling(it's the old one).

Overall it seems like the shirt Amazon is selling, although still branded as Champion, is made from a different plant(with lower standards). With all that said, this is still a decent quality muscle tee. The fit and neck hole is pretty loose, but overall the material is serviceable.
