Petzl Sirocco 2: a hybrid design engineered for the mountains

The Petzl Sirocco 2 features a hybrid construction combining several advanced materials:

  • Expanded polypropylene (EPP) shell for impact absorption
  • Polycarbonate outer shell
  • Expanded polystyrene (EPS) liner for targeted protection
  • Lightweight and durable polyester straps

This structure achieves high durability while maintaining a minimal weight. The helmet meets the Petzl TOP AND SIDE PROTECTION standard, ensuring optimal protection against lateral, frontal, and rear impacts.

Field of view and comfort: a helmet designed for climbing

The open front profile of this helmet provides an extra-wide upward field of view, essential for climbing and mountaineering. The edges remain out of sight, allowing for an unobstructed view of the route.

The fully adjustable fit, achieved through head and chin straps, ensures a precise hold. The minimalist buckle with locking cover prevents accidental loosening, even in technical conditions.

Ventilation and head torch compatibility

The Petzl Sirocco helmet offers continuous airflow thanks to:

  • Vents
  • Breathable internal padding
  • Grooved liner promoting air circulation
