Stephan Siegrist has climbed the Eiger North Face over 40 times. In addition to these highlights, Stephan Siegrist impresses again and again with his versatile climbing projects.

Clothing plays a vital role in survival

"As a professional alpinist, the right clothing plays a vital role in survival. It has to offer me safety - especially the first layer I wear on my body. It has to stay dry and wick away sweat from my skin, as well as insulate well in cold conditions. The highly functional products from X-Bionic give me this security and at the same time give me energy - this is crucial on my expeditions, which often take place in difficult and extreme conditions. The compression also improves blood circulation and helps me recover faster. Thanks to X-Bionic, I can wear a lighter second layer, which allows me to reduce the overall weight of my clothing. X-Bionic is great for many different applications - from ice climbing to expeditions."


Martijn Jegerings, Chief Marketing Officer of X-Bionic explains, "We are convinced that Stephan Siegrist and X-Bionic are a perfect match. His expertise and years of experience in surviving under the most extreme conditions in alpine terrain give him a unique perspective and a very clear view of what he needs to succeed in the mountains. We are always looking for ways to improve an athlete's performance through the use of our patented and award-winning technologies. Having such a Swiss legend on board to wear our products and test them in extreme conditions is of great value to us."
