No more lost ski masks! The VIJO is the best choice for children and teenagers looking for a perfect versatile helmet and the best comfort, including that offered by a retractable visor that slides INSIDE the helmet protecting the lenses from scratches/knocks that may occur when you transport/store it. The built-in mask also guarantees perfect vision and can be used with one hand. Thanks to the increased protection of the foam edge, the airflow is reduced to a minimum. It is always fully compatible with all masks! The VIJO has a removable X-Dry lining, so it can be worn with a cap under the helmet to keep the ears of young people warm.
