The high-performance version of our popular Formula Pants is cut for skiers who need extra room in the thighs for a comfortable day on the mountain. Four-way-stretch, waterproof and lightweight Toray Dermizax™ fabric allows easy movement and keeps out wet snow. Toray 3DeFX+™, a thin, elastic, insulating layer with an amazing warmth-to-weight ratio keeps legs warm without slowing you down. When you start to heat up, unzip the ventilation system on the back of the legs to bring you back to the ideal temperature. These ski pants for men have a comfortable, elastic waistband and modern, international fit in the groin for comfort. We've inserted a panel in the lower back for improved breathability, improved the waist-adjustment system and engineered the waist band to fit higher in the back for extra protection from the elements.
