The Sirocco climbing helmet from Petzl is the ultimate upgrade for demanding climbers and mountaineers. Designed to offer an exceptional ratio between lightness (only 170 g) and protection, this helmet is a must-have for your mountain adventures. Thanks to its full-coverage design lowered at the back, it provides enhanced protection over the entire head while guaranteeing optimum comfort with permanent ventilation. The Sirocco's hybrid design, combining an EPP foam shell and a rigid shell injected with EPS foam, ensures unrivalled robustness without compromising weight. The open front profile enhances the upward field of vision, allowing you to keep an eye on your route without perceiving the helmet's edges. What's more, adjustable sizing and ski touring compatibility make this helmet a versatile choice for all your outdoor activities.
