What is a "lab coat"?

A lab coat is a knee-length, lightweight overcoat typically made of cotton or polyester, that is worn by medical professionals and scientists in laboratory and clinical settings to protect their clothing and skin from contamination. They are usually buttoned in the front and have long sleeves, with some featuring pockets for holding pens and small tools. Lab coats are designed to provide a barrier between the wearer's body and the potentially hazardous or contaminated materials they may encounter in their work. They come in various sizes and colors, with white being the most common, and can be easily laundered and reused.
