2Lane, I have Shoei Multi-Tec with the PinLoc inserts for anti-fog. They work great, just be very careful cleaning them, ANY type glass cleaner, dawn, joy or whatever will "craze" the inside coating. A little water and dab with a micro-fiber works great. I have used FOG-CITY inserts before on full face helmets and they are without fail the most amazing things going, the Shoei's work as well, I have ridden @ nite at 30 or so degrees with the shield fully closed and totally fogged all around the edge of the insert, but totally clear on the insert. Nite in fall and winter, early morning on humid days.. there is just nothing better than a fog insert until it rains, THEN they are worth millions because even at a stop light they remain clear.
FYI
