A puffer vest is a sleeveless outer garment designed to provide warmth without the bulk of full jackets. It is typically filled with synthetic insulation or down feathers, making it lightweight yet effective in retaining heat. Puffer vests often feature a quilted design, which helps distribute the insulation evenly, and they come in various colors and styles. These vests are popular for layering, as they can be worn over long-sleeve shirts or under heavier coats. They are ideal for outdoor activities like hiking or casual outings, offering both comfort and style. Many brands, such as Patagonia and North Face, produce high-quality puffer vests.
