Bill Murray, the legendary actor and comedian, is launching his own lifestyle and apparel brand called William Murray Golf.

The collection represents a partnership between Murray Brothers LLC, including actor Bill Murray, and Resignation Media, owners of the entertainment website thechive.com

The line promises to “break away from traditional golf apparel by bringing a new look and feel to the industry with a little irreverence and a lot of style.” It includes polos, T-shirts, shorts, hats and the world’s first golf button-down, which has become the actor’s signature look on the course.

Professional golfer and 15-year PGA Tour veteran Pat Perez will serve as William Murray Golf’s first brand ambassador.

The entire product line will be available online Thursday, October 20, at williammurraygolf.com and available through their exclusive partner, thechivery.com.

Bill and his brothers worked closely on all aspects of the line to ensure the brand’s authenticity, from creative design to color patterns to production. The youngest of the six brothers, actor Joel Murray, says the family’s history has played a vital role in their love of the game.

“Growing up caddying helped us learn about strict adherence to rules and subservience,” said Joel Murray. “Caddying also helped us learn we had no interest in either.”

Bill Murray’s adoration of golf is well documented and extends far beyond his famous Hollywood role, Carl Spackler in Caddyshack. Along with his brothers, he hosts an annual charity golf tournament, Murray Bros. Caddyshack Charity Golf Tournament, in St. Augustine, FL, with the mission to better the lives in communities across the country.

On September 21, in celebration of Bill Murray’s birthday, William Murray Golf will release a special Chicago-themed polo and two hats a month before the full line’s launch. A portion of proceeds from these opening day sales will go to the Murray family’s favorite charity in Chicago, Mercy Home for Boys & Girls, which helps break the cycle of neglect and abuse for Chicago-area children and young adults ages 11 to 21.

“We’re going to create a whole new level of excitement to the game,” said John Resig, president of Resignation Media. “Our clothing will focus on bringing high quality, performance elements with creative designs for golfers who want to keep it light.”
