Uramasari Worker Jacket - Olive green Twill Seiran weave

The Uramasari Worker Jacket reimagines traditional workwear through a sharp, contemporary lens. Crafted from a premium technical blend, this short-length jacket delivers rugged utility in a clean, modern silhouette.

Its defining feature is a thoughtful, graphic asymmetry. Seiran weave slash across the lower pockets, while matching contrast lining is hidden along the inner placket and under-collar.
