Built for sled runs or ski slopes, Gordini Juniors' Stomp mittens stand up to the elements. Breathable shells, Megaloft synthetic insulation, AquaBloc inserts, and moisture-wicking lining keep hands warm, dry, and comfortable all day. AquaBloc is Gordini's proprietary waterproof, breathable, windproof technology. Exclusively engineered for hand wear, AquaBloc is an insert technology that allows moisture accumulated from within the glove/mitten to escape and provide for breathability and enhanced warmth and comfort. For extra warmth, these kids' mittens have zippered handwarmer pockets. Textured palms help grip ski poles and sled handles. The best way to clean and dry Gordini gloves and mittens: wipe clean with a damp cloth and mild soapy solution if needed, and then hang-dry away from a direct heat source. Do not machine dry or dry clean Gordini gloves or mittens.
