Multi-pitch climbing is a demanding and exhilarating discipline that involves ascending rock faces over multiple pitches, often spanning several hundred metres. Unlike indoor or single-pitch sport climbing, where routes are generally short and well-protected, multi-pitch climbing is an outdoor sport that requires careful preparation, good physical fitness, and the right equipment. Among the essential gear, a climbing helmet plays a crucial role in ensuring both safety and comfort. It protects the head from falling rocks as well as from harsh impacts against the rock face.

Why choose an ultra-light climbing helmet?
When spending several hours, or even an entire day, on a crag, the weight of your gear becomes a crucial factor. A lightweight helmet helps reduce fatigue and improves comfort around the neck, which is essential for maintaining performance and optimal focus throughout the climb. Here are a few reasons why a lightweight helmet is indispensable for multi-pitch climbing:
- Reduced fatigue: A slightly heavier helmet can cause strain on the neck and shoulders, especially after hours of climbing. A lightweight model minimises this strain, helping to conserve energy for technical sections.
- Enhanced comfort: Lightweight helmets are often designed with breathable materials and efficient ventilation systems. This helps keep the head cool and reduces sweating, which is particularly important during summer climbs or in direct sunlight.
- Freedom of movement: A lightweight helmet provides better mobility, which is crucial for climbers who frequently need to look up to find holds or bolts, as well as for belayers who need to keep an eye on the lead climber. It also reduces the load during the approach hike.
- Safety: Despite their lightweight design, modern helmets offer optimal protection against falling rocks and impacts. Like all climbing helmets, they comply with the CE EN 12492 standard, but their construction differs from traditional models. Classic mountaineering and climbing helmets feature a rigid outer shell across the entire surface for both vertical and lateral protection. In contrast, ultra-light climbing helmets use a hybrid construction. This hybrid design typically combines a rigid, puncture-resistant shell on the top of the helmet with an EPS foam (a type of rigid expanded polystyrene) shell around the sides to protect the rest of the head.

Construction of an ultra-light climbing helmet

Helmets compatible with ski touring
At present, ski touring does not have a specific helmet safety standard. It is possible to wear either a CE EN 1077 certified skiing helmet or a CE EN 12492 certified climbing helmet. However, some brands, such as Petzl and Edelrid, have developed their own internal certification for ski touring: Petzl’s Top and Side Protection certification and Edelrid’s PCSR-002 11.2019 certification. These standards ensure strong side impact protection. Whichever ultra-light climbing helmet you choose, you can also use it for ski touring in winter.
