Mountaineering requires both good physical preparation, knowledge of high-altitude terrain and technical training. The garments that make up your kit must be high-performing enough to withstand extreme conditions. Here are some tips on how to dress for mountaineering.
Choosing breathable and insulating mountaineering clothing
Multiple layers of clothing are needed to withstand the cold at high altitude. The upper body requires at least three layers, while the lower body requires at least two.
Choosing thermal underwear that breathes is essential for mountaineering. When you’re active, it helps wick away sweat; when you stop, it helps retain your body heat. Choose your t-shirt and thermal leggings carefully.
Your second upper-body layer should provide insulation. A fleece jacket or an insulated jacket is well suited to this activity.
The importance of protective clothing for mountaineering
Protective clothing is essential when dressing for mountaineering. For high-altitude use, softshell is not recommended — hardshell is the better choice.
Three-layer jackets and overtrousers offer the technical performance and durability needed in the mountains. Their membrane sits between the outer fabric and the inner lining. These garments resist abrasion, which is essential when moving against rock. They are also waterproof to withstand bad weather.
When choosing your mountaineering protective jacket, make sure it has reinforcements in key areas, underarm ventilation zips and an adjustable hood with tightening points that fits over a helmet.
Good mountaineering trousers have articulated knees for greater freedom of movement. Gaiters are also essential for mountaineering: they close the gap between your trousers and boots.

The role of clothing for the extremities
Protecting the extremities is non-negotiable in mountaineering. These parts of the body are the most exposed to frostbite and cold injuries. Gloves must be warm, protective and durable. Mountaineering gloves feature a lining to keep you warm, reinforced leather palms, and excellent abrasion resistance. We recommend wearing thin, warm liner gloves underneath your mountaineering gloves.
Protecting your head — and especially your ears — is equally important. Beanies are generally made from merino wool, synthetic or hybrid materials. Wearing a liner beanie or a balaclava under your mountaineering helmet is also essential to prevent heat loss.
Finally, socks and footwear must be suited to your activity. Shoes specifically designed for mountaineering provide excellent grip and must be chosen with care.
Choosing the right clothing for mountaineering matters. You need garments that are warm, breathable and lightweight, but above all abrasion-resistant. They complement basic mountaineering equipment (ice axe, crampons, helmet…) and help you move through the high mountains in the best possible conditions.
