Korean War Era US Army fatigue cap. This is the way they were worn during that time period, very stiff like a coffee can style. Color is OD green has 2 air holes on each side. No size tag but I wear a size 7 and it is just a little small on my melon. Cap is very clean no sweat stains, no rips, no smells and no repairs. This is a great cap for your collection, you don't see a lot of these in this condition.

Good Luck and Happy Bidding. Free shipping with-in the continental USA.
