These limited-edition hats were a promotional giveaway from the Sharks game on April 6, 2024. New, unused. One Size. Measures about 23 inches around but the band inside is elastic and so adjusts to many different sized heads--children, women, and men all wearing them well at the game. 

Player William Eklund posed wearing one of these straw hats after scoring his first NHL hat trick during this game: https://www.nhl.com/sharks/news/william-eklund-wears-sharks-straw-hat-after-1st-nhl-hat-trick-x1298 

(included this photo for FUN only-WILLIAM EKLUND DID NOT WEAR THIS HAT I AM SELLING. Mine is a new hat that I got at the game)
