I'm pretty sure Winning patented it, they'd be dumb not to.
And what makes Winning special is the whole package, craftsmanship, quality, fit, the materials they use, all their know how. You can't take one of their ingredients, go to Pakistan and come up with a Winning headgear. All the things I just mentioned will be totally different, it'll be a different product. And it's not like you can come out and say "Hey buy our stuff, we use the same foam Winning uses!". So having the same foam won't help much.
People should be a little creative and come up with something they believe in, not make money off of what other companies came up with and rip them off. It's not gonna work anyway.
