STIO Womens Fernos Insulated Jacket (2026)

Redefine cold days with warmth and breathable, stretch performance, with the touch of style that transforms a training jacket into an everyday essential. Lightweight synthetic PeakFill® Active insulation is mapped for more warmth in the core and less in the arms, offering a sleek fit with more stretch, faster recovery and quicker drying times than traditional lofted insulation. 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.
