Petzl Sirocco Helmet

An ultra‑light climbing and mountaineering helmet for ambitious climbers and alpinists who prioritise low weight without sacrificing protection. It balances minimal mass with extended coverage for technical climbs.

Benefits

• Very low weight: 170 g (size M/L) reduces fatigue on long approaches and alpine routes.
• Hybrid construction: EPP shell with injected EPS crown and polycarbonate cover for impact absorption at low weight.
• Extended rear coverage: elongated back enhances protection of the crown in side and rear impacts.
• Effective ventilation: multiple vents and internal air channels maintain airflow during intense activity.
• Low front brim and low‑profile buckles: improved upward vision and comfortable use with harnesses and eyewear.

Typical use: sport climbing, alpine ascents and fast mountain approaches in conditions where minimal weight and good ventilation are priorities.
