So it fits just fine if you downsize. I'm 6'2 and 160 lbs and I bought a M. Fits great. I will say though that the colors are not as what it seems to be, take every shade they have in the pictures and tone it lighter 2-3 shades. Their army green colored one is barely green, and the tan one is INCREDIBLY close to my own skin tone so I won't wear it often. The one toned shirt that came the closest to the picture is the blue one. (I bought blue, tan, green and grey). Great shirts if you enjoy lightweight and a sports shirt material used in the shirt.
