Windproof

The technical membranes applied to fabrics used for mountain activities play a crucial role in providing protection against adverse weather conditions. One of their most important characteristics is wind resistance, which ensures thermal comfort in exposed and windy environments.

Wind, especially in mountainous regions, can cause the body to lose heat rapidly—a phenomenon known as the windchill effect, where the perceived cold increases significantly. To mitigate this effect, technical membranes block the passage of wind, acting as an impermeable barrier to air while maintaining the fabric's breathability.

There are two types of membranes with windproof properties: microporous and non-porous membranes. Microporous membranes, such as those using expanded polytetrafluoroethylene (ePTFE) technology, are composed of a structure with tiny pores. These pores are small enough to prevent wind from penetrating but large enough to allow water vapour to escape, thus enhancing breathability. On the other hand, non-porous membranes use materials like polyurethane (PU), which provide a solid barrier against wind while allowing moisture to evaporate through a chemical process known as diffusion.

In the production of clothing for skiing, wind resistance is crucial to prevent heat loss and protect the body from low temperatures and biting winds. Our ski jackets and trousers feature windproof membranes, allowing wearers to stay warm and comfortable even in extreme conditions. Moreover, these membranes are integrated into the fabrics in a lightweight and flexible manner, ensuring freedom of movement.
