Mountaineering helmets are mainly made from two types of material: ABS plastic for a hard, resistant outer shell, and expanded polystyrene or polypropylene for the shock-absorbing inner lining. Helmets can also incorporate composite materials, such as carbon or aramid (Kevlar), to reduce weight while increasing strength.
A helmet must be comfortable and remain stable on the head, whatever the conditions of the climb. To achieve this, it's essential to choose a helmet with a precise adjustment system that's easy to manipulate, even when wearing gloves. Helmets with adjustment knobs on the back are particularly appreciated for their ability to adapt finely to different head shapes and sizes.
Ventilation is an important criterion, especially during prolonged exertion or in hot conditions. Sufficient, well-placed openings reduce condensation inside the helmet and improve thermal comfort. Some models offer ventilation adjustment options, which can be a major asset in a variety of environments.
For advanced mountaineers, helmet compatibility with other equipment is crucial. Check how easily you can attach a headlamp, goggles or even a face mask. Some helmets are specifically designed to allow easy and secure integration of these accessories.
The helmet you choose must comply with current safety standards. In Europe, CE EN 12492 certification guarantees that the helmet has been tested and approved for mountaineering. This standard ensures that the helmet can withstand a wide range of impacts and forces. Always check that the helmet is recent and has not been recalled or reported for manufacturing defects.
The durability of a helmet is another factor to consider. A well-maintained helmet can last for many years, but it is recommended to replace it after a severe impact or every 3 to 5 years, depending on usage. Regular inspection for signs of wear or damage is crucial to ensure safety. Cleaning should be carried out according to the manufacturer's instructions, usually with lukewarm water and mild soap, and the helmet should be stored away from sunlight and heat.
Choosing the right helmet for mountaineering is not a decision to be taken lightly. It's essential to consider safety, comfort and compatibility with other equipment. A well-chosen helmet will not only increase your safety in the mountains, but also your enjoyment, allowing you to concentrate fully on the climb. Take the time to test different models and make sure that the helmet you select meets all your specific needs as an advanced mountaineer.
