Nice shirt, but sizing isn’t ideal for big and tall builds
Size: XX-Large Tall, Color: Black
The shirt itself is decent quality and looks good, but the fit wasn’t great for me. If you’re a big and tall guy, this may not be the best option. The material has some stretch and feels comfortable, but the overall cut runs smaller and doesn’t offer much room in the shoulders or torso. It works better for slimmer or more standard builds. If the sizing works for you, it’s a nice-looking shirt. Just be aware that it’s not very forgiving in the fit if you need extra room.

Good value
Color: A-white, Size: X-Large
Great shirt for the price! Lightweight, comfortable, and the fit is true to size. Non wrinkle material, Great for golf/athletic shirts or blanks for dtf or embroidery.

Clean & classy look, but make sure you buy a size bigger because it runs small.
Color: A-black, Size: 4X-Large
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!
