Heavyweight Cotton Mens Workwear Jacket | Vintage Amekaji

Heavyweight Cotton Mens Workwear Jacket

Timeless Japanese-Inspired Layering Built For Everyday Wear

Heavyweight Cotton Mens Workwear Jacket, cut from a dense 415g woven cotton that has real substance to it without turning stiff. A clean zip front, fold-down collar and relaxed vintage fit give it the quiet Japanese Americana shape that wears just as well over a tee as it does under a coat.

The matte surface texture picks up character with wear, and the neutral black colourway sits with almost anything: raw denim, wide-leg trousers, washed tees, flannel shirts, cargo pants, leather boots or sneakers.

Key Features

415g Dense Woven Cotton: substantial in the hand and still breathable enough to layer.
Full Metal Zip: a proper metal pull rather than a lightweight plastic one.
Fold-Down Collar: structured, and sits clean open or closed.
Dual Slanted Welt Pockets: angled for hands and set flush to the body.
Adjustable Cuff Buttons: tighten the sleeve over a knit or push it back.
Relaxed Vintage Fit: a clean oversized drape without the bulk.

Built Around Authentic Amekaji Style

Not a fast-fashion piece with loud branding and disposable cloth. This is a workwear jacket built on proportion, texture and function, drawn from classic Japanese workwear and heritage Americana, the kind of thing that ages into something better rather than wearing out.

Is This Jacket Pure Cotton?

Our supplier documents the cloth as heavyweight woven cotton at 415g but does not certify the exact fibre composition, so we will not describe it as pure cotton. It handles like a dense cotton twill. If you need the precise composition before ordering, message us and we will confirm it with the warehouse.

How Heavy Is The Fabric?

415g, which puts it well above a shirt jacket and into proper light outerwear. It is warm enough over a knit on a cold morning without being an insulated winter coat. There is no lining or padding.

What Kind Of Zip Does It Have?

A full-length metal zip with a metal pull. It is described to us as YKK-style rather than YKK, and we have no documentation confirming the brand, so we do not claim it as YKK.

What Does Amekaji Mean?

Amekaji is Japanese shorthand for "American casual". It describes the Japanese reading of US workwear and Americana, usually heavier cloth, honest construction and a relaxed silhouette, worn as everyday clothing rather than costume. This piece sits squarely in that tradition.

How Fast Is UK Delivery?

Stock is held in the UK and ships domestically, so there is no waiting on an overseas order. UK delivery is free on orders over £100. If your order is delayed it will be because that size has sold out and we are replenishing it, and that will take no longer than 10 working days.
