Thick quality polo shirt, just maybe not for Golfing.
Color: Black/Blue, Size: Medium, Color: Black/Blue, Size: Medium
This shirt was a lot thicker than I imagined. It's built well and fits as intended, but as far as a golf shirt it is quite heavy, and I would feel as though it would cause overheating or sweating. Very thick shirt, possible better for colder golfing days and still look good. I enjoy the color and pattern. It is soft and comfortable, again just a little thinker than anticipated, not a quick dry material, but a fully cotton blend. Decent value for the money and would consider pitching others in the future but most likely not for golfing in general.

Good shirts
Color: Black Diamond & Dots, Size: Large
Nice shirt. Pattern true to pictures. True to size unless you're 6'2 and you want to leave the shirt untucked, it's a bit short.
