Vertex

The chinstrap is multifaceted, having two breaking strengths for working at height or on the ground. The outer shell of the helmet provides shock absorption through deformation, and also protects the user from electrical, chemical, and potential fire hazards.
 
The Petzl Vertex is compatible with the range of modular helmet accessories, allowing attachment of: eye shields, headlamps, helmet protectors, nape protectors, name tag holders, hearing protection, and replacement components.

Features:
Very comfortable:
Six-point textile suspension adapts perfectly to the shape of the head
CENTERFIT feature allows perfect centering of the helmet on the head, thanks to its two side adjustment wheels
FLIP&FIT system allows the headband to be positioned in a low position, guaranteeing that the helmet fits securely on the head. The system folds into the shell for easy storage and transport
Comes with interchangeable standard comfort foam
Protection designed for work at height and on the ground:
DUAL chinstrap allows the worker to adjust chinstrap strength in order to adapt the helmet to different environments: work at height (EN 12492) or on the ground (EN 397). The clip has two positions, corresponding to two uses: high strength, limiting the risk of losing the helmet during a fall, and low strength, limiting the risk of strangulation if the helmet is snagged while the user is on the ground
Shock absorption achieved through deformation of the outer shell
Unventilated outer shell protects against electrical hazards, molten metal splash and flames

Modular accessories:
Eye shield with EASYCLIP side attachment system for easy installation
Petzl headlamp with mounts, or headlamp with elastic headband
Helmet protector keeps the shell free from soiling and paint splash
Nape protector provides effective sun and rain protection for the nape of the neck
Nametag holder allows user to be easily identified
