The insulation in your Gordini glove depends on its purpose. Some gloves contain more than one kind of insulation, for optimal performance.GooseDownis Gordini’s premium goose down insulating concept. GooseDown is designed to never clump or let in the cold. A unique construction captures the down in small chambers, ensuring that the fill is evenly distributed and will not migrate. These gloves and mitts are all insulated with 600-fill-power goose down. GooseDown mitts have wraparound insulation for ultimate warmth, while GooseDown gloves have back-of-hand insulation with Megaloft synthetic insulation on the palms to optimize your warmth and dexterity.DownTekis a treated, water-repellent down that allows moisture to wick off the insulation, rather than compressing the down fill. This technology allows the down to retain all insulation properties even in high-moisture conditions.Megaloftis a synthetic insulation that will not become compacted, providing warmth and ensuring good manual dexterity. It is a favorite for palm insulation, where consistent loftiness is key.Primaloftis a synthetic, water-resistant microfiber insulation that allows breathability and warmth without bulk.
