As for sizing, make sure you buy a size up because it runs kinda small, (you’ll thank me!). Quality is good, but the best feature-it has a dress collar polo with some color around the neck and buttons, which gives it a clean and classy look, (which I’m a fan of), the comfort of the polo is about average. I absolutely recommend!

Nice shirt

Color: A-royal Blue, Size: X-Large

This is a decent shirt. It feels nice against the skin and fits like it should. It feels a little cheap, but that could be because it’s thin. Kept me comfortable in Florida heat and humidity!
