A puffer coat is a type of outerwear designed to provide warmth in cold weather. It is typically filled with insulation material, such as down or synthetic fibers, which creates air pockets that trap heat. The coat's quilted design helps to keep the insulation evenly distributed, preventing cold spots. Puffer coats often feature a water-resistant or waterproof exterior, making them suitable for various weather conditions. They come in various styles, lengths, and colors, catering to different fashion preferences. Popular among outdoor enthusiasts and urban dwellers alike, puffer coats are a practical choice for winter wear.
