What is insane asylum jacket?

Insane asylum jacket, also known as a straitjacket or straight jacket, is a garment that is used to restrain a person's arms and torso tightly to prevent them from harming themselves or others. It was commonly used in psychiatric hospitals and asylums in the 19th and early 20th centuries as a means of controlling patients with mental illnesses. Insane asylum jackets were typically made of canvas or strong cotton cloth and featured long sleeves that were tightly strapped together across the chest. The jacket was designed to be almost impossible for the wearer to remove and was often used as a form of punishment and confinement. In recent times, straight jackets have largely been replaced by less restrictive types of restraints in mental health facilities.
