Inspired by beach jackets from the 1920s, the BATT Harbor Jacket brings together traditional knitwear techniques and vintage outerwear design. The densely knitted fabric combines four different yarns, including slub cotton, five-color kasuri cotton, and two types of wool, creating a richly textured surface with subtle variations in color. The reverse is brushed for a soft, fleece-like feel, while a detachable collar and cow leather trim add versatility and structure to the relaxed silhouette.
