Climbers, come out of your shells. By borrowing the plastic used to reinforce car bumpers, Petzl ditched the usual outer layer to bring you a UIAA-certified helmet for about half the weight of your average lid. Unlike the crunchy foam inside most hard shells, the Sirocco’s expanded polypropylene is durable and flexible, maintaining good impact absorption through repeated impacts.
- Made of expanded polypropylene, which has a high rate of energy absorption, and does not support microbial growth (to reduce odours)
- Shell has excellent ventilation and is adjustable
- Comfort foam is quilted, lined with absorbent fabric, and removable for washing
- Lightweight polyester adjustment system further reduces weight
- Minimalist buckle saves weight and holds it securely
- Open profile front lip improves visibility
- 2 front clips and rear elastic keep your headlamp secure
