Looking for Answers about Nike SB Icon T-Shirt II - Men's?

I usually get XXL cause the chest is 50-52 and I like my shirts loose. so what im wondering is, is this shirt a tighter or looser fit if i usually get 50-52?

Do the reviews do justice? I was curious to know if I need to buy a size bigger. I do like my shirts to be exact fit and not too big and not too small. In other words, I don't want the shirt to be tight on me but I don't want the shirt to be Big and look like a snuggie. If it helps I typically wear a size Medium on RVCA shirts. The RVCA shirts that fit smaller ( they all differ) I wear a Large. I don't know how the exchange or return policy is, but maybe I can order 2 of each color that I want and return the sizes that don't fit. Or if you guys can give me exact measurements on the shirt specs. (Sleeve, Length and Width) that would be awesome. thanks Yoshi
