The term 'Polar Coat' is a type of outerwear that is typically made of waterproof and windproof material. It is also known as an ANORAK, which is a 6-letter word commonly used to describe this type of coat. Polar Coats are designed to keep the wearer warm and dry in cold and wet weather conditions. They are often lined with fur or synthetic insulation and feature a hood to protect the head from the elements.
