A waterproof coat is a type of outerwear designed to keep the wearer dry in wet conditions. Made from special materials that repel water, these coats often feature sealed seams and water-resistant zippers to prevent moisture from seeping in. They are commonly used in rainy weather, during outdoor activities, or in professions that require protection from the elements. Many waterproof coats are also breathable, allowing moisture from sweat to escape while keeping rain out. Popular styles include raincoats, hiking jackets, and ski jackets, each tailored for specific activities. These coats are essential for staying comfortable and dry in unpredictable weather.
