From October 1–7, 2025, a limited-time pop-up store will be held on the 1st floor (Promotion Space 11) of Hankyu Men’s Osaka, showcasing apparel and accessories made with Brewed Protein™ fiber.

The event will feature special items created by four notable Japanese brands, each exploring Brewed Protein™ fiber through their own creative perspectives: doublet, DISCOVERED, LIBRIO MENDONÇA, and Kids™. Together, the brands present a lineup of eight items, including T-shirts, jackets, and caps. This marks the first attempt to curate a cross-brand collection featuring Spiber’s materials in a department store setting.

Featured items include:

• DISCOVERED – “WOOL & BOA MA-1” jacket (¥143,000)
• LIBRIO MENDONÇA – “GARMENT-DYED SWEATSHIRT HOODIE” (¥44,000)
• Kids™ – “GLOW GROW CAMP CAP” (from ¥11,000)
• Brewed Protein™ Capsule T-Shirt (¥25,300) – A special collection of five graphic T-shirts (four designs by MASU, DAIRIKU, TSTS, and doublet, plus one secret design) sold in capsule toy gacha format. Each shirt features unique artwork inspired by “cultivation” and “fermentation”, reflecting the processes used to create Brewed Protein™ materials.

The project was made possible through an invitation from Hankyu Department Store, which resonated with Spiber’s Brewed Protein™ fiber and mission of sustainable manufacturing. Having four diverse and influential brands from Japan’s fashion scene interpret our material through their distinct styles in one venue represents a significant new step for Spiber. We hope visitors will enjoy discovering the charm and potential of Brewed Protein™ fiber—and find new ways to enjoy clothing—through this initiative.
