A puffer jacket is a type of outerwear designed to provide warmth in cold weather. It is typically filled with materials like down or synthetic insulation, which create small pockets of air that trap heat. The jacket's quilted design helps to keep the insulation evenly distributed, preventing cold spots. Puffer jackets often feature a water-resistant or waterproof outer shell, making them suitable for various weather conditions. They come in various styles, colors, and lengths, catering to different fashion preferences and activities. Popular among outdoor enthusiasts, they are commonly worn for activities like hiking and skiing, as well as for everyday use.
