Merchandise from the “Training Camp BBQ” series—a collaboration between the TV anime “Haikyū!!” and the outdoor brand “Coleman”—will go on sale in early September 2026. The lineup consists of five items: a Walker pouch, the “Take 6” cooler, a Lumière lantern featuring the Karasuno High School design, the Walker 25, and a hot sandwich maker. Pre-orders are now being accepted on “Anime Store.JP,” the online store for the collaboration café.
