The VERTEX helmet is very comfortable, thanks to its six-point textile suspension and CENTERFIT and FLIP&FIT systems, which guarantee that the helmet fits securely on the head. The adjustable-strength chinstrap makes it ideal for both work at height and on the ground. The unventilated outer shell protects against electrical hazards, molten metal splash and flames. 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. The high visibility version features a fluorescent outer shell with phosphorescent clips and reflective bands, for optimal visibility of the worker, day or night.
