I've been experienceing fogging problems with my tz1 so i decided to try out some antifog visor inserts from Fog City to see if they could help. Long story short they rock! They work alot better than any of the sprays i've tried before. I just rode home in the rain with them on for the first time and it was so much better than without it. Used to riding in the rain was pretty rough because my shield would fog then i'd crack it to unfog it and get wet or hit in the eyes with rain this was much better no fogging at all where the insert was. Sorry if this is kinda rambly i'm just really pleased with this product. Now to go find some hot coccoa i'm cold and wet .
