PETZL Vertex Vent Comfortable Ventilated Helmet Red Climbing. Excellent condition. Used once. Model #: A010CA02 * Very comfortable:
- six-point textile suspension conforms 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 transportation
- 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 these 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
- vent holes with sliding shutters allow the ventilation to be adjusted as needed, while wearing the helmet
