BIOTOP and Levi’s announce limited ‘501® ORIGINAL GREY SHIP’ denim

BIOTOP has announced a special collaboration with Levi’s for the release of the ‘501® ORIGINAL GREY SHIP’ denim. The product features the classic 501® straight silhouette with a unique blue-grey color achieved through a grey over-dye process on indigo denim.

The over-dye technique allows the original indigo to gradually emerge through wear and washing, creating a changing color profile over time. The item is priced at 19,800 yen.

Pre-orders will begin on the BIOTOP official online store on August 28, 2026. General sales are scheduled to start on September 15, 2026, through the BIOTOP online store and physical locations in Tokyo, Osaka, Fukuoka, Kobe, and Sapporo.
