There’s a clue in the name: the jacket is reversible; flipped inside-out and worn on the reverse. There’s no trick to it: just remember to pull the arms through. Both sides have a small rounded collar. The jacket’s lighter side has light horn buttons; the other side has dark ones.

The jacket is made from two complementary shades of grey-green wool-tweed from a woollen mill in West Yorkshire. It’s a robust, heartily textured cloth; a warm, hard-wearing, trusty tweed. Up close it can be seen that it comprises many shades of grey and muted greens.

The jacket has in-seam slouch pockets on both sides (left). These pockets are almost completely hidden when not in use — but they’re always there if you need somewhere to warm your hands.

The dark green side of the jacket has a button-through patch-pocket at chest (right) while the light green side has a document / A4-sized pocket and smaller wide pocket (see picture at top of page). It goes without saying that one set of pockets becomes internal depending on which way one wears the reversible jacket.

The chap here is 5ft 10in (177cm) and wears a size small.

The wool hails from a mill founded in the early 1800s in the heart of the Heavy Woollen District in Yorkshire. Dyeing, blending spinning, weaving — it all happens on the same premises, ensuring raw fleece’s transformation into top-grade cloth is subject to the same five generations-worth of expertise.

The dark horn buttons are made — that’s cut, dyed, and polished — by the last remaining manufacturer of horn and corozo button in England. Based in the West Midlands, the factory has been in the hands of the same family since opening in the mid-1800s: five generations of top-quality button-making know-how.

The garment is made and finished in a small factory in North London, which excels with outerwear, shirts, and trousers. It’s a place of meticulous cutters, unflappable seamsters and seamstresses, and a well cared-for and marvellous-looking contraption for making button-holes.
