Thin enough for shoes and thick enough for boots, Bivouac lambswool socks provide warmth and comfort in any situation. Features: Odor Resistant: Odors are caused by bacteria in sweat. Wool naturally provides antibacterial protection, reducing unpleasant odors. Thermoregulating: Wool naturally regulates temperature, keeping you warm in winter and cool in summer for optimal comfort year-round. Natural Warmth: Wool traps the body’s natural heat, providing exceptional insulation for cozy comfort even in extreme cold. Plus, wool remains warm even when wet. Moisture Control: Wool can absorb up to a third of its weight in water without losing its insulating properties. It draws moisture away from the body and releases it outside the sock, keeping you warm and dry. Composition: 50% Lambswool, 48% Nylon, 2% Spandex Made in Canada
