What was cool back in the 60's that sold wool

What was cool back in the 60’s that sold wool? You wouldn't believe it these days. People were really into wearing regatta jackets, especially during the British Invasion. Patrick McGoohan popularized the style of dress here in America when he played on "The Prisoner" and you often saw famous actors like Richard Dawson wearing them in public. Back then, they were made of 100% wool and really did that industry a favor.
