I normally wear an XL, I’m 5’11” at 185lbs, but I ordered the 2XL, and it definitely runs small, because it fits like an XL.The other thing, is I’m a little disappointed with the coloring, as it’s supposed to be HOT PINK, but as you can see in the photo, it’s more like a reddish pink, not quite neon red, but definitely not hot pink.But it is comfortable. So I’m going to keep it.Remember to size up!
