Pea jackets, also known as PODS, are a type of outerwear that originated in the 19th century. They are typically made of heavy wool and feature a high collar and large buttons. The name comes from the fact that they resemble the shape of a pea pod. Pea jackets were originally worn by sailors in the British Royal Navy, but have since become popular among civilians as well. They are often seen as a fashion statement, and are available in a variety of colors and styles.
