I have this Fulmer flip up. It's very comfortable and light weight. The air flow is minimal at best, but I wear a a 1/2 helmet on warm days. On cold days, the visor fogs up when your not rolling. The clear visor is polarized and so are my sunglasses. The use of 2 polarized lenses produces weird color halos that are distracting, so I need to get a tinted visor.
