My brother-in-law just bought a Russian Fighter Pilot helmet at an Military Surplus store. It has a drop down clear shield and a drop down shaded shield. Good for bright day or night ridin. Any regular helmets out there that have both mounted? All I've seen is where you can remove one (shaded for day) and attach a clear or light yellow one for nights. It'd be nice to have both mounted and pull down whichever you needed at the time without having to remove and replace.
