This women's jacket is the winning formula of KJUS engineering and craftsmanship for a comfortable day on the mountain, which is why it comes back year after year with new details and refinements. Ultra-stretchable fabrics and KJUS FAST Thermo Core™ insulation work together to move with you as you make your way down the mountain without restrictions. This style balances waterproof protection with breathable comfort thanks to the premium Toray Dermizax™ membrane. The KJUS AC-Vent™ anatomically placed in the sleeves offers quick and easy ventilation with the tug of a zipper, while the four-way-stretch Graphene lining intelligently disperses high-heat zones across the fabric to help keep you comfortable. A Graphene-lined pocket is the perfect place to stash your phone and keep it from losing its charge in cold conditions. Adjust the fit and function with the detachable hood and adjustable hem and powder skirt for a comfortable fit every time you wear this jacket.
