Nice, but a little snug
Size: Large, Color: Navy 177
I like the material, it does a better job than most shirts of being wrinkle free. The sizing is a bit small, I have a gut and if feels snug, whereas my other shirts (mostly LL Bean) do not.

Nice shirt!
Size: X-Large, Color: Blue Red White 161
A very nice checked shirt. It is mostly iron free. The material, although cotton has a stiff feeling. If you forget that drawback, it's a nice shirt. So reasonably priced.
