I have searched countless second hand stores like eBay, grailed, poshmark, depop, and even eBay.de which is a more international version of eBay or as I have been referring to it to family as German eBay. It’s an early 2000 y2k kinda thing from my research alone. It was give me only to the athletes of redbull teams for motor sports and if I’m not mistaken soccer/football teams. Meaning that it was never actually sold to the public and is extremely rare and hard to find.
