Designed for dexterity, Gordini Men's Mountain Crew mittens perform best in frosty conditions. AquaBloc inserts protect you against all the elements while letting your hands breathe. Water-resistant 600-fill DownTek insulation with 75% goosedown and 25% goose feathers keeps your hands warm with minimal bulk. Moisture-wicking lining keeps your hands from feeling sweaty. Rugged nylon shells have synthetic leather palms and genuine cowhide trim and finger areas. Neoprene cuffs with pull-tab closures make it easy to get these mittesn on and off and fit comfortably under jacket sleeves. 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.
