The two biggest names in technical materials join hands in the Synthesis Glove. Waterproof, breathable GORE-tex® inserts keep your hands dry so they don't get clammy - the easiest way for fingers to catch cold and lose dexterity. To guard against frigid winter weather, Thinsulate™ Insulation lays a protective barrier between your skin and Mother Nature. With friends like these, you don't have enemies.
