Hey, I was recently given a very cool mello yello full-face by my girlfriend's dad. It was bought as 'native GBH protective garb' along with a baseball bat when he lived in PNG for a few years. He had intended to buy a new bike on his returnto aus, but that didn't happen. It was purchased ~1970-75. Think i should wear it?? It's never been used- just sat in a garage for 30yrs. Anyone know if the aus design standards have changed a lot since then or if there is any other reason why i shouldn't use it?? Cheers, Chris
