i personally have learned that I prefer to size down on my u-neck tees. I'm 6'4" 175 and wear a large villian hoody and medium u-necks. I think u should get small u necks. I know the mercer is meant for that symmetrical layered look with the villains but I don't really care I like the u necks with them too. I just think the fit of the unecks is so sick and unique. Mercers are nice but they don't do it for me like the uneck tees. I also think the mercers might fit slightly longer and slimmer by a hair. The comix blend is real cool too. Worth buying. If anyone wants to trade me anything for my large grey kitos I'd like to size down to a medium or maybe get something else from JE. Perfect condition never washed.
