A windbreaker is a lightweight jacket designed to protect the wearer from wind and light rain. Typically made from synthetic materials, it features a close-fitting design to minimize air resistance. Windbreakers are popular for outdoor activities like running, hiking, and cycling, as they provide comfort without adding bulk. These jackets often come with adjustable features, such as hoods and cuffs, to enhance their effectiveness. Many windbreakers are also packable, allowing them to be easily stored in a bag when not in use. They are a practical choice for anyone needing a versatile layer for changing weather conditions.
