Clothes designed for sub-zero temperatures sometimes incorporate a number of layers of insulation, a sturdy waterproof and windproof outer shell, and options like sealed seams, adjustable cuffs, and insulated hoods. A parka designed for Arctic expeditions exemplifies one of these specialised attire.
Safety from extreme chilly is crucial for sustaining core physique temperature and stopping hypothermia or frostbite in difficult environments. Traditionally, such safety relied on pure supplies like fur and down. Developments in artificial supplies and textile know-how have led to lighter, extra environment friendly, and infrequently extra ethically sourced options. This evolution has broadened accessibility and improved efficiency in various cold-weather actions, from scientific fieldwork to high-altitude mountaineering.
