The Vizen face shield protects against electric arc hazards. This full-coverage shield offers face and eye protection while preserving peripheral vision. It is easily installed on Petzl Vertex and Strato helmets, thanks to the Easyclip attachment system. It also has scratch-resistant and anti-fog coatings. When not working, it pivots quickly from work position to storage position on top of the helmet.
