There's a Custom Cap company called Lucky Seven Caps, that allows you to choose different hat styles, as well as different patches. I picked one up, and it's an awesome looking hat, that's really comfortable! The patches are incredible quality. Sadly, you can't buy them standalone, as they have to come on a patch.
I picked up the last patch, in all black, on a black military hat. It's super comfortable! You can order online, and shipping is really fast. I would definitely recommend it for fans of TRON, and basically any other cult movie. But we all know why we're here.
Affiliates are Still Closed, until I decide a way to design a box for them.
