One Reason Professional Golfers Wear Hats

From a 2018 article:

PGA TOUR Pro Hat Deal Value: $250,000–$500,000

“The front of the hat is your No. 1 real estate. On the high end, this deal generally includes other inventory—bag, equipment—as well. If you’re a Top 30 player, you’re definitely making seven figures on this. For a Top 10 guy, you’re looking north of $3 million and getting close to eight figures for the most marketable players in the world. For this deal, a player will be obligated to, on average, commit to giving a company three to four appearance/promotional days per year.”
