HAT TRICK: For fans of Labubu and “The Monsters” series by Kasing Lung, the ultimate flex might be a one-of-a-kind baseball cap customized by the Hong Kong illustrator — complete with eyes, ears and fangs.

It’s one of 16 caps being auctioned for charity by Joopiter and God’s True Cashmere, the luxury knitwear label founded by Brad Pitt and Sat Hari.

The duo invited a host of contemporary artists to reimagine the classic baseball cap, including Etsu Agami, Hiroshi Fujiwara, Jennifer Guidi, Joel Mesler, Jonas Wood, Josh Sperling, Kelly Akashi, Kenturah Davis, Mary Weatherford, MR, Rashid Johnson, Shara Hughes, Tavares Strachan and Yoshitomo Nara.

Pitt and Sari, an energy healer, also customized one of the cashmere caps, a new addition to their six-year-old line, which also produces beanies, a bucket hat and one fedora style.

Online bidding for the “Artists for Impact” auction opens Thursday and runs through April 7, with proceeds from each lot benefiting the charity of each artists’ choice.

Some of the caps will be exhibited at a God’s True Cashmere pop-up at Joyce in Hong Kong from Thursday through April 2, coinciding with Art Basel art fair there.

In addition, the Los Angeles-based brand and Joopiter are offering a limited-edition collection of cashmere baseball caps in four colorways that will be sold on their respective websites, in addition to Joyce in Hong Kong. A subsequent retail rollout will see the caps offered at Harrods in London, Just One Eye in Los Angeles and the God’s True Cashmere store in Seoul.

Founded in 2022 by Pharrell Williams and dedicated to collectibles, Joopiter has organized sales in collaboration with Jackson Wang, BamBam and Sébastien Jondeau, the late Karl Lagerfeld’s closest confidant.
