The Stio Women's Fernos Insulated Jacket redefines cold days with warmth and breathable, stretch performance, with a touch of style that transforms a training jacket into an everyday essential. Lightweight synthetic PeakFill® Active insulation offers more stretch, faster recovery and quicker drying times than traditional lofted insulation in a sleek fit. The dynamic outer face wears with a soft hand and has a PFAS-free water-repellent finish that resists light precip and dries quickly. Zippered chest and handwarmer pockets stash what you need and an adjustable hem seals out chilly updrafts.
