This is a Workers 2024AW sports jacket. I purchased it at a store in Tokyo. I've only tried it on, and haven't worn it outside. It's made of duck fabric, so it's a bit stiff, but I think it's easier to wear than a denim jacket. I wear a size 38 in the same brand's BD shirts, but a size 40 in this jacket was the perfect fit. The measurements are approximately: length 64cm, width 58cm, shoulder width 47cm, and sleeve length 60cm.
