Comfortable, a bit tall
Color: Dark Blue, Size: X-Large
Great shirt, very comfortable. It's a little tall/long, so 4 not 5 star. I'm going to shop around for different brands, but this will be my fallback because it mostly works for me.

Nice T-Shirt
Color: Army Green, Size: Medium
My husband likes the shirt. Wears it and the others like it all the time. It's very soft, didn't shrink in the W/D and is true to size (Large fit 6'2" 190 lbs). Only complaint I have is the binding on the neck. It wasn't cut properly before being attached and is not smooth. This tells me this is a second.
