This is a very nice, casual shirt that could be worn as an under shirt or as a regular shirt. I paired it with a polo and it looked great. You could wear it as gym wear, for a hike, working in the yard, sports practice, or just on the go. It's well made and very comfortable. Wears kind of big, but once you launder the shirt, it does shrink a bit. No problems though. Fits as expected. Would buy again.
