A Seaman's Jacket is a type of outerwear worn by sailors and other seafarers. It is typically made of heavy wool and has a double-breasted front with large buttons. The Peacoat, also known as a P-coat or REEFER, is a classic style of Seaman's Jacket that has been in use since the 18th century. It is characterized by its short length, broad lapels, and double-breasted front. The REEFER is a more modern version of the Peacoat, featuring a longer length and a single-breasted front. Both styles of Seaman's Jacket are designed to provide warmth and protection from the elements while at sea.
