Where Can I Find an Authentic Hells Angels Leather Vest?

I've recently become interested in motorcycle culture and have noticed a few individuals wearing what appeared to be a hells angels leather vest. I'm extremely curious—are these vests available to the general public, or are they only for members? I don't want to disrespect any club traditions or violate any unwritten rules. Also, are there any replicas or similar styles that capture the look without breaking any rules? Any suggestions on where to purchase high-quality motorcycle vests (with or without patches) would be greatly appreciated. I simply want to get the style right without offending anyone. Thanks in advance!
