That logo is a special Open Championship insignia designed specifically for the tournament _ part of a company-wide effort to produce specially designed commemorative gear and apparel for staff players to sport in each of the four majors.
If you’re into that sort of stuff, replica versions of the hats, stand and staff bags are for sale, with TM’s MSRPs as follows: hat–$24.99, staff bag–$499, stand bag–$189.
From the news release:
Two specially logoed bags have been created for each TaylorMade Tour Staff player playing in the Open Championship. After the event, each player keeps the bag and autographs the other. All autographed bags are sold to a private collector, and the proceeds are donated to the First Tee, an initiative of the World Golf Foundation that creates new facilities and access to golf with a special emphasis on kids who otherwise may not have an opportunity to experience the game.
Interesting. And some pretty clever marketing that’s already paying dividends, too, as Thursday’s nice tight shot of Sergio’s head cover can attest.
