Women’s insulation from Stio gives you warmth that packs light and moves with you. We make two types of insulation: down and synthetic. Down offers the most warmth for its weight and packs down small, which makes it ideal for cold, dry days and chilly lift rides. Synthetic insulation keeps you warm even when it gets damp and dries quickly, so it works well for high-output days, wet snow, and shoulder-season hikes. This collection includes insulated jackets, vests, and hoodies to wear as a midlayer under a shell or on their own when temperatures drop. Look for lightweight options for active days and warmer, higher-loft styles for the trailhead or the lift line. Every piece is designed in Jackson, Wyoming, with a fit made for layering. Add a women’s shell on top for wind and weather protection.
