The Petzl Vertex Vent helmet is very comfortable, thanks to its six-point textile suspension and fitting systems, which guarantee that the helmet sits securely on the head. The adjustable-strength chinstrap makes it ideal for both work at height and on the ground.
It has ventilation holes with sliding shutters to allow airflow through the helmet. With its potential for integration of a Petzl headlamp, hearing protection, and multiple accessories, it is an entirely modular helmet, thus responding to the specific additional needs of professionals.
