Garments designed for sub-zero temperatures prioritize thermal insulation, wind resistance, and moisture management. Such apparel typically includes parkas, insulated trousers, base layers, gloves, hats, and specialized footwear. An example would be a multi-layered system incorporating a moisture-wicking base layer, a fleece mid-layer, and a down-filled parka with a waterproof and windproof outer shell.
Protection from severe cold is crucial for maintaining core body temperature and preventing cold-related injuries like hypothermia and frostbite. Historically, materials like fur, wool, and leather provided warmth. Advancements in textile technology have led to the development of synthetic materials like polyester fleece and Thinsulate, offering superior insulation and moisture-wicking properties in lighter, more durable packages. This evolution allows for increased mobility and comfort in extreme conditions, facilitating activities from scientific expeditions to winter sports.
