Hey folks! I put some photos in my build thread but thought it might be useful in the helmet section. I just received a vintage snowmobile helmet from the 70's that I purchased on ebay. I gutted the helmet for the chinstrap setup. I know it's not 100% perfect but I think that it could be a viable option for those looking for this type of thing. You can find many of the helmets for under $20. I paid $7 for this one plus $8 for shipping. Anyhow, I'd be interested in your opinions on it. Take care.
