Inconsistent sizing. I bought multiple colors. My purpose was to be able to conceal carry. I usually wear a large, but some of these colors fit like a medium, and some are fine and how a beefy tee should be.

In the pictures:
The grey is how I expected them to fit. Heavy and just enough room to conceal comfortably without printing.
The navy blue, is slightly smaller. I would be worrying about printing too often to wear it.
The light blue is way too small. It is slim fit. It fits like a medium compared to the grey.

I bought more colors, mostly other greys, but they have not arrived. It does not matter, because in the first three, they all fit differently. I expect the same with any other color. I am disappointed, but honestly, it's hanes, and I expected to be. Hanes/FOTL and other like brands you may find at wal-mart or like stores are all made inconsistently through outsourcing to different countries. The quality control varies.

I returned all of them. I will keep looking elsewhere, but it seems like all the ones that are dependable have pockets, and that is something I really don't want. My next option is Carhartt and Riggs by Wrangler. I am far from country, or a baggy shirt wearer, but I need to be confident that I am not printing and the shirt weight will allow it to fall past my gun without having to adjust in public. Those two options seem to be the only viable option. I own pants in both, and they are roomy like I like them. I also wear 5.11 and other brands, but those shirts are ridiculously expensive.

TL;DR The sizing and quality control is inconsistent. Typical hanes quality. Skip these and try another brand.
