The VERTEX helmet is very comfortable, with a six-point textile suspension as well as CENTERFIT and FLIP and FIT systems, which provide a secure fit 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 the ability to integrate a Petzl headlamp, face shield, hearing protection, and multiple accessories, it is an entirely modular helmet, meeting the additional needs of professionals.
