Insulated jackets are specially designed outerwear that provide warmth by trapping body heat. They are typically filled with materials like down feathers or synthetic fibers, which create air pockets that act as insulation. These jackets are popular for outdoor activities in cold weather, such as hiking, skiing, or simply walking in winter. The outer layer of insulated jackets is often made from water-resistant or waterproof fabrics to protect against rain and snow. Many models also feature adjustable hoods, cuffs, and hems to enhance fit and comfort. Brands like North Face and Patagonia are well-known for their high-quality insulated jackets.
