Remarkably lightweight for ambitious climbers and mountaineers. The Sirocco helmet was designed to give you an exceptional weight-to-protection ratio (170 g). Lower in the back, the design provides greater coverage and offers enhanced protection over the entire head. Its low profile and superior ventilation give you all-day comfort.

Ultra-lightweight design — 

• Perfect for long days at 170 g.
• Minimalist buckle and adjustable webbing for increased comfort and lighter weight.
• Hybrid construction with an EPP (expanded polypropylene) foam shell and rigid crown injected with EPS (expanded polystyrene) foam

Enhanced protection — 

• Designed in accordance with Petzl’s Top and Side Protection label.
• Designed for optimal protection against impacts to the side, front, and rear of the head.

Maximum comfort in action — 

• Open front profile makes the helmet rim invisible to the user and offers an unobstructed field of view.
• Headband and chinstrap webbing are fully adjustable.
• Low-profile buckle locks in place to help keep the chinstrap from loosening unintentionally.
• In addition to ventilation holes, the interior foam and liner feature integrated air channels for better air circulation.
• Two front clips and rear elastic band for securing a headlamp to the helmet.
