Nice shirt!
Color: Black, Size: Large
When I lost weight and hit my goal I wanted to purchase new clothing. I discovered Coofandy on Amazon and could not be happier. This line of clothing is great. I have purchased a handful of shirts and shorts and liked all of them. This shirt fits well, I tried a medium initially and it was a bit too small so I moved up to a Large. Prior to my weight loss I was always an X-large. Shirt looks nice and fits great. I have this shirt in 3 colors now.

Great shirt, a bit large in arms
Color: A - Moon Gray, Size: Medium
I really like the cut and texture of the shirt. The only thing I would say is it is loose in the arms unless you’re a body builder. My arms are toned, muscular, but more lean than thick, so if you like a snug sleeve this is probably not for you. I’m 5’9” 180bs for reference and wear a medium.

Check the size chart and reviews!
Color: Black, Size: 3X-Large, Color: Black, Size: 3X-Large
Bought this for my husband and if i didnt check the reviews I would ordered it too small. He normally wears a XL in T-shirts but he has very large arms so the 3XL in this fits him comfortably. The material is a bit stretchy so he could have probably taken the 2XL but I am satisfied with how the 3XL looks on him. He looks so good!

Size discrepancy
Color: Wine Red, Size: Small
I like the look and feel of this shirt, but I originally bought a medium and it was too big, so I bought a small. Both shirts are the exact same size. It is labeled on the collar as a different size, but it's the same. If anything the small is slightly larger
