Gecko Helmet with half-glass
I recommend a Gecko helmet, but with half face cover. The glass will not get fog when is half-face. As option to cover the face I used neopren mask, just like assaul troops are using, covering the nose and mouth and ears and neck. Its easy to use (velcro at the back. In fact, the mask was made for assault troops, but similar one (made of polar, which is not as good) everybody can get in ski-shop.
