A coverall is a one-piece protective garment designed to cover the entire body, including arms and legs. It is commonly used in industries such as construction, manufacturing, automotive, and healthcare to protect workers from dirt, chemicals, heat, or other hazards. Coveralls come in various materials, including cotton, polyester, and specialized fire-resistant or waterproof fabrics, depending on the intended use. Some designs include hoods, zippers, or elastic cuffs for added protection.
