Will be back to riding this season after a few years off.....now with 'must have' prescription glasses. How do you, that wear glasses, handle the fogging in closed helmets? I have a heated shield, but that won't help the glasses. Do you all just ride with the shield cracked open? ~Dawned on me this morning when I walked the dogs with a balaclava on, and was miserable!! Couldn't see a damn thing!
