Open-face helmet Mammut Haute Route Black White Hybrid shell construction

The Mammut Haute Route Black White is an open-face helmet engineered for alpine skiing, ski mountaineering and related outdoor pursuits. It combines a hybrid shell construction with targeted ventilation and a secure 360° fit system to deliver protection, low weight and comfort during ascents and descents. The design includes large front vents and internal air channels to reduce fogging of goggles, elastic straps and front clips for easy attachment of goggles or a headlamp, and a lightweight, helmet-compatible beanie for cold conditions.

Advantages

The hybrid shell construction pairs a partial hard shell with in-mold foam to balance impact resistance and overall lightness, while the triple certification ensures conformity with standards for skiing, mountaineering and cycling. The advanced internal airflow system and large vents maintain a comfortable microclimate during high-effort climbs and fast descents. A 360° spherical wheel adjustment system with multiple positions provides a secure, adjustable fit for a wide range of head shapes, and removable washable padding supports hygiene and comfort over extended use.

Suitable for

• Alpine skiing and ski touring
• Ski mountaineering and racing
• Multi-sport fast tours combining climbing and biking
• Cold-weather approaches where a lightweight beanie is needed
