Bought helmet for cross country trip. Extremely comfortable, even in closed position. Can actually feel air coming in thru chin vent when open. All functions easily performed with left hand under way. Slight fogging in very cold air, but not in line of sight. Actually, so comfortable I lower chin bar and close face shield whenever possible, which is new for me since I always wore open face helmets and thought I would never get used to full face. Ninety miles per hour never felt so good.
