Quality item at a very reasonable price.
Size: X-Large, Color: Black Red
I've gone with the coofandy brand for the past few years. They make good quality shirts at a reasonable price and the fit is usually consistent. They're a little difficult to get the packing wrinkles out but it can be done. I wish they would label what style each shirt is because they make several different ones. Overall very satisfied.

Cool Cuban Shirt
Size: Large, Color: Black Dark Gray
Looks nice and lightweight. I hand washed it and it turned out well. I used an iron to lightly press it. Overall the wrinkles were not bad. Would recommend
