Michael Jordan has a unique relationship with underwear. In 2019, he celebrated 30 years as a spokesperson for Hanes, which is 15 years more than he spent playing in the NBA.

If you’d prefer a more intimate perspective on his undergarment habits, sports auction house Lelands is offering what they claim is a pair of boxer briefs owned and worn by the basketball great. The auctioneer says that the apparel “shows definite use,” though doesn’t specify as to the exact nature of said use.

The underwear comes from John Michael Wozniak, a onetime security guard of Jordan’s who apparently received a number of items as a gift from the NBA star, including suits, ties, and belts that are also up for auction.

Jordan memorabilia has been a consistently popular category in the sports collectibles world. In May 2020, a pair of game-used Nikes from his 1985 rookie season sold for $560,000.

Bidding on the underwear is up to $1300 and will likely continue to rise through the end of the auction on September 25. They do not, however, appear to be manufactured by Hanes.
