Garments designed for sub-zero temperatures prioritize warmth, durability, and protection from the elements. Such apparel typically incorporates advanced materials like down insulation, synthetic fibers, and waterproof or water-resistant membranes. Examples include insulated parkas, expedition-weight pants, fleece mid-layers, insulated gloves or mittens, and thick, warm socks.
Protection against severe cold is crucial for maintaining core body temperature and preventing cold-related injuries like hypothermia and frostbite. Historically, humans have utilized natural materials such as fur and wool for warmth. Advancements in textile technology have led to the development of highly effective synthetic materials that offer superior insulation, breathability, and moisture-wicking properties, enabling safer and more comfortable experiences in extreme environments.
