Lightweight and comfortable design:
two-part liner, EPP (expanded polypropylene) and EPS (expanded polystyrene) for reduced weight

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

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 or on the ground. 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 liner
ventilation holes allow airflow through the helmet
