Shop the Kjus women's classic Kjus Formula ski pants. The Women's Formula Pants have entered a new season of refinement. Kjus adjusted the fit in several ways to increase comfort and offer a more flattering silhouette, plus included the lightweight KJUS FAST Thermo Core™ insulation. A new, engineered waistband sits higher in the back for a more comfortable wearing experience, and an improved waist-adjustment system to help you customize the fit every time you wear these pants—an updated Toray Dermizax™ for breathability and waterproof protection.
