Weatherproof jackets are designed to protect the wearer from adverse weather conditions such as rain, wind, and snow. They come in different styles and materials, including waterproof and breathable fabrics such as Gore-Tex, which allow moisture to escape while keeping the wearer dry. Some weatherproof jackets also have insulation to keep the wearer warm in cold temperatures. These jackets are often used by people who work outdoors, such as construction workers, landscapers, and utility workers, as well as outdoor enthusiasts such as hikers and campers. They are available in a variety of colors and sizes to fit different body types and preferences.
