Heavy jackets are designed to provide warmth and protection in cold weather. They are typically made from thick materials like wool, down, or synthetic fibers, which help insulate the body. Many heavy jackets also feature additional elements such as hoods, zippers, and pockets for added functionality and comfort. These jackets are popular during winter months and are often worn for outdoor activities like hiking, skiing, or simply commuting. Brands like North Face and Columbia are well-known for their durable and stylish heavy jackets, catering to various needs and preferences in cold climates.
