A lab coat is a protective garment worn by professionals in scientific and medical settings. Typically made of cotton or a cotton-blend fabric, lab coats are designed to shield the wearer from spills, stains, and other hazards. They often feature long sleeves, a front button closure, and pockets for carrying tools or instruments. Lab coats are commonly used in environments such as laboratories, hospitals, and research facilities. They help maintain cleanliness and safety while allowing easy movement. In addition to their practical uses, lab coats can also signify professionalism and authority in fields like medicine and science.
