Ok, I looked at the profiler and it looks like the thermal lense is just a reqular lense coated with anti fog stuff that wears off. I was wondering if there were any masks that have double pained lenses and are quick to take out, clean, and put back in. I know JT has these lenses, but they are impossable to take out, and even harder to put back in.
Is this mask any good? http://cgi.ebay.com/ws/eBayISAPI.dll...m=300549572732
