There are two hooks and a rear elastic for attaching a headlamp, and it's compatible with the VIZION eye shield.

Using the Petzl Sirocco helmet is straightforward. First, adjust the headband and chinstrap to fit your head comfortably. The magnetic buckle on the chinstrap makes it easy to fasten and unfasten. If you're using a headlamp, you can attach it to the two hooks or the rear elastic. You can also use the VIZION eye shield if needed.
When it comes to safety, always make sure the helmet is properly adjusted before starting your climb or hike. Check for any signs of damage, like cracks or dents, regularly. If you notice any issues, stop using the helmet and replace it.
To keep your helmet in good condition, store it in the protective storage bag when not in use. Clean it with a mild soap and water solution. Avoid using harsh chemicals as they can damage the materials. Also, don't expose the helmet to extreme heat or direct sunlight for long periods, as this can affect its performance.
