Nice shirts! Fit perfectly!
Color: Dark Green, Size: Large
REALLY nice shirts! Bought dark green and black for my 23 year old son before he left for his six month cruise job to East Asia and they look to not wrinkle at all, plus they fit perfectly and look great! He's 5' 10" and about 170 lbs and wears a large. It fits a little loose, but he likes it that way. I would highly recommend these shirts!

Color is off, but still a nice shirt.
Color: Brown, Size: X-Large, Color: Brown, Size: X-Large
The shirt is great as far as quality. Material is very nice. Hubby wears an XL, and I bought the XL and it fit him perfectly. He is 5'11" and weighs 210lbs.
The reason I gave a 4 star, and not a 5 star is because I ordered the brown color. When you look at the brown option on the color option, you will see from my pictures posted that I did not receive a brown shirt. What I received was more like a rust color or a copper color. I kept it because I actually liked it. But Amazon needs to do better with their color descriptions. If you're looking for a genuine brown color, this is not the shirt for you.
