The original U.S. military roundel - adopted in 1917 - and precursor to the roundel currently in use on American military aircraft, the red circle would eventually be permanently removed from the design during WWII so as not to be mistaken with the markings of a Japanese flag.
This is a lightweight hoodie with a slim fit. For men, we *STRONGLY* suggest ordering a size up from your usual size.
Bought the roundel hooded sweatshirt. Ordered up in size, which was a good move (M -> L). I dig the way it fits. It's a thinner fabric which makes it form fitting. Might buy another, might not, I'm crazy... watch out.
