Comfort is one of the most important factors, as these are clothes you’ll be wearing throughout the season. A poorly placed seam or fabric that’s too tight will soon become noticeable. It is essential to stay focused on your activity rather than on any discomfort you may feel. Opt for stretch fabrics for close-fitting clothes to ensure complete freedom of movement.

  

• To prepare for changing conditions, you’ll need to add or remove layers throughout the activity; choose compact, lightweight clothing that will fit easily into the bottom of your rucksack without weighing you down. Some windproof jackets can even be folded away into their own pocket. They can then be carried by hand or clipped onto your belt, which is particularly handy for minimalist trail runs, for example. 

  

• There are two ratings shown on your protective jacket (or trousers):
 o   The Schmerber rating for waterproofing.
 o   The MVTR rating (g/m²/24h) for breathability.

 
We recommend choosing a garment with a rating of at least 10,000 Schmerber and g/m²/24h to ensure optimum protection and ventilation.
A jacket rated at 20,000–25,000 Schmerber is more suited to powder snow activities such as freeride or ski touring.
For example, a product labelled ‘Membrane 20K/10K’ means that the membrane has a waterproof rating of 20,000 Schmerber and a breathability rating of 10,000 g/m²/24h.

The three-layer system – how does it work?

Choosing the Right Upper Height

   

The upper height refers to the part of the boot that surrounds the ankle. This criterion directly affects freedom of movement, stability, and the level of protection.
