- These highly stretchable ski pants are made in a windproof recycled nylon/recycled polyester/elastane mix which ensures great flexibility and comfort. They are reinforced with a recycled polyamide/polyester/elastane mix on exposed areas to provide extra durability where needed. To prevent wet snow from soaking up, the bottom hem is reinforced with 200D recycled GORE-TEX. Together, these three materials create the perfect balance between weight, comfort, durability, and sustainability.
