The Masters winner is presented with the jacket each year.
On Sunday night, millions of sports fans will watch one golfer put a jacket on a rival on front of a television camera in Butler's Cabin.
When you put it like that, the Green Jacket ceremony at Augusta sounds rather silly, but the jacket itself is one of sport's biggest prizes.
The Green Jacket was first presented to a Masters winner in 1949 to Sam Snead. Although Snead was the first winner to receive the jacket, he was the winner of the 13th tournament. All previous champions were subsequently awarded the famous piece of clothing.
Although the first jacket was presented to a Masters winner in 1949, its idea dates back almost another 20 years. Bobby Jones, the designer of Augusta National was playing at Hoylake in The Open Championship in 1930.
In a player's reception before the tournament began, he noticed each captain at the Liverpool course wore a red jacket to the event. From there, the idea was set in his head.
Although not opened until 1933, the green jacket was incorporated for Augusta National members to wear in 1939. The jacket was a way of showing other fans, who knew the course, and to ask for advice with directions from one hole to the next.
All members are required to leave their jackets in the club, with the exception on one person. The reigning Masters champion.
Over the past 12 months, Danny Willett has brought his prized possession with him around the World, but once he returned this week, it most now stay in the clubhouse.
People like Seve Ballesteros and Gary Player have previously flouted the rules, but it's a given that all green jackets must stay on Augusta National property.
Each April, the sporting world becomes intrigued by the Green Jacket, in it's unusual shade. It's called Pantone 352.
