Inspired by the "Sack Coat" first produced in the mid-1800s, this jacket offers a relaxed fit, allowing versatile layering options across seasons.
This interpretation of a workwear classic has been crafted from proprietary fabric, developed by Japan Blue and woven in Okayama. The 10oz denim features khaki beige-dyed weft yarns, giving it a deadstock-like vintage feel. Despite being relatively lightweight, the fabric is woven with high density, providing both firmness and a satisfying aging process over time.
