Know Zai skis? One of their ski models even has a core made of stone, sourced from local mountains. ZAI’s research led to the development of carbon fibre stone (CFS)—created by wrapping stone in a special carbon fiber laminate, making it not only pressure-resistant but also flexible. Worth checking out! Enjoy the Photo Gallery: Zai Ski Factory Tour in the Swiss Alps at Core77, one of our favorite sites.
