Lab coats are protective garments worn primarily in laboratories and medical settings. They are typically made of cotton or a cotton-blend fabric, providing a barrier against spills, stains, and contaminants. Lab coats often come in white, although they can be found in other colors as well. They usually feature long sleeves, a front button closure, and pockets for holding tools or notes. These coats are commonly worn by professionals such as scientists, doctors, and students during experiments or clinical procedures. In addition to protection, lab coats help maintain a sterile environment and can signify the wearer's role or expertise in a specific field.
