A waterproof jacket is a type of jacket with waterproof function, usually made of waterproof materials such as coatings, film layers, or waterproof fabrics. A waterproof jacket can effectively prevent rainwater from penetrating the interior and keep the body dry. They usually have characteristics such as water resistance, breathability, and wear resistance, making them suitable for outdoor sports, hiking, and rain protection needs in daily life. Some waterproof jackets also have adjustable hats, cuffs, and waistlines that can be adjusted as needed to provide better waterproof effects.
