I recently bought a Nolan N87 lid and I'm really pleased with it - good fit, comfortable, relatively quiet, etc. Better than the Sharks and AGV's I've had previously.
But it has one issue that's annoying me - my glasses start misting up even in not cold weather. During the summer I can live with it as it just open the visor a sliver and it clears. But not so good with the cold and rain coming.
I've not really had this issue before, or at least they clear quickly once moving. I've put in a Foggy mask which seems to help a little, and spray stuff on them. I'm guessing it's something to do with the airflow. Any suggestions? Could try swapping to the standard screen (got a tourer fitted ATM), and take out the screen thingie under the chin, but neither are appealing in the cold....
Any ideas?
