I normally use an XXL for Rokfit T-shirts. They are loose without being baggy and retain shape around the chest and arms. I found with the grey tie dye that it had no shape in the arms or chest. Im not sure if it was just perceived because the material is lighter? But I am considering sizing down for the other two colors.
Still a nice shirt but no way this light-a material can be hammered as much in the gym as the others.
NB : This shirt was bought as a gift, I am a verified purchaser previously.
