Petzl - STRATO® VENT Helmet

• Optimal protection:
  - the DUAL chinstrap 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 liner
  
• Lightweight and comfortable design:
  - two-part liner, EPP (expanded polypropylene) and EPS (expanded polystyrene) for reduced weight
  - 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
  - ventilation holes allow airflow through the helmet
  - comes with changeable absorbent comfort foam
