The Burton AK Oven Mitt. Burton's legendary Oven Mitt just got an upgrade from the previous version, which frankly most of us didn't think was possible. By wrapping the fingers in leather and loading it with insulation, these hand jackets are warmer and more durable than ever before. Features include triple-fill goose down, 15 ounces of Primaloft® insulation, Hydrofil wicking liner, and ultra-breathable WINDSTOPPER® fabric from GORE-TEX®. If you're a person who does any serious winter exploring, or if your hands are just always cold, you need to pick up a pair of these.
