Hygge keeps you cozy all winter long. Powered by clim8 intuitive heating, it adjusts and personalizes your warmth and comfort no matter the chill. Clim8 is a battery-powered, heated glove technology designed to auto-regulate and respond to fluctuations in body temperatures and changing weather conditions. Gordini's proprietary, built-in waterproof, windproof, breathable inserts keep hands dry and synthetic insulation and moisture wicking lining keep hands comfortable. Wrist leashes ensure you don't drop these heated mittens off the chair lift or along the trail. These mittens should fit snug but not tight. If you are between sizes, size up for maximum comfort. To determine your glove size, measure in inches both your hand circumference (flat, from crook of thumb around outer edge of palm) and hand length (fingertip to the bottom of the palm). Women's sizes: S (circumference 6.5” and length 6.5”), M (circumference 7” and length 7”), L (circumference 7.5” and length 7.5”). Spot clean and air dry.
