Was a sled head for years, snowmobiled in temperatures that you’d have to open your face shield and spend 10 or 15 minutes in the warm up shack to thaw the helmet enough to get it off your head with tearing your moustache off or ripping your ears off. Sleds sure run hot at -35 but keep your thumb off the bar or you’ll melt some pistons. Expensive been there done that.
