I like these shirts, light weight (I live in the south) and quality seems OK, but probably should have exchanged them for XL's. I'm 5/9 160 lbs , med build, size large is normally plenty big for me. I thought maybe they would be OK despite them seeming more like a size med. I'm not sure if they shrank to much, but they just don't seem to have enough room in the shoulder/pit area for my build. I don't know if I'm comfortable wearing them, I bought a few pairs. So I have to decide if I should try the XL's but I wonder if they will be to big? Oh well they are not are not that expensive, so I'll have to decide. Since I want my t's to be comfortable I will probably end up donating the large's I bought. If you like your shirts form fitting/not roomy (or you have skinny build) you may like them, other wise you may consider going up a size, for a roomier fit. Also the V-neck is shallow, not much wider then a crew neck, other then that and the sizing they seem OK. I have bought other Hanes t's like this before (size large, not nano) and never had a problem with fit. These shirt's lose stars for fit and V-neck drop is shallow/narrow..
