Bandai's official shopping site, Premium Bandai, will release outdoor items (backpacks and parkas) in collaboration with "JoJo's Bizarre Adventure." The "JoJo's Bizarre Adventure x OUTDOOR PRODUCTS Aja's Red Stone Daypack" (9,240 yen) is a collaboration with the Los Angeles-based outdoor goods brand, "Outdoor Products." It features the Aja's Red Stone and Lisa Lisa's crest, two key items from the story, as motifs. The "JoJo's Bizarre Adventure Speedwagon Foundation Parka" (7,140 yen) zip-up sweatshirt faithfully reproduces the official logo of the Speedwagon Foundation, founded by Robert E. O. Speedwagon, a character in the series, through embroidery and print. Available in gray and navy. Pre-orders for both items will begin on the 16th, with shipments scheduled for late October (shipping fees not included). The products are also sold at Village Vanguard, a bookstore that sells miscellaneous goods, and on Shueisha's online store for character goods, Mekke!.

Outdoor Products was founded in Los Angeles in 1970. In 1973, the Outdoor Recreation Group was formed and the company began manufacturing outdoor products. In 1986, the company name was changed to Outdoor Recreation Group, and the Outdoor Products name became the flagship brand. Brands specialized in various sports, such as hunting, skiing, and snowboarding, are available. Currently, the brand is loved in over 60 countries.

"JoJo's Bizarre Adventure" has released collaboration items with various brands, including sneakers in collaboration with Converse and watches in collaboration with Seiko.
