Open-face helmets are probably the next choice to full-face ones when it comes to the level of protection they are capable of offering. Even if they do not cover every side of the head, leaving the chin area open, they still are capable of keeping the head of the rider safe in case an accident occurs and in most cases will allow him to walk unharmed. Open-face helmets have a major disadvantage in terms of comfort and protection: they lack a face shield and the rider will have to wear a pair of specially designed goggles in order to keep insects and other particles that can be encountered on the road away from his eyes. You won't have to worry about high temperatures when it comes to open-face helmets because they allow a natural air circulation. On the other hand, noise levels can be pretty high, especially in some models.
