A medium-length work jacket is what this is, in a nutshell, with its most notable feature being the one thing it doesn't have — namely a collar. Rather, the jacket has an open, curved front — which is what you see on old engineer and railroad-type jackets — and a thick placket panel that runs down both sides.
The buttons are horn, and are dark in colour and matte in finish. Being as they're only a step or two from nature, each one is different, in terms of shade and marking. Those at the front are attached through eyelets and a metal ring — "butcher's buttons", sometimes they are called — and are thus removable.
There's a seam that runs across the chest of the engineer jacket, from the placket, into which are tucked two pockets of handily-sized-for-wallets-and-mobiles dimensions. The storage credentials of these pockets are augmented by the pleat which runs perpendicularly from the cross-chest seam.
That pleat, mentioned above, when it reaches the lower half of the jacket, is also the starting point for the large main pockets, which sit at hip-height. Large is the operative word: these pockets wrap around the sides of the jacket, stopping at the seam at the rear, which rests approximately at kidney coordinates.
Curious here is that that seam at the back, where the pocket stops, is also the shoulder seam. It runs up, see, over and around the shoulder. That's how the sleeve is attached. It is a type of "grown-on" sleeve — an arcane genre, where the sleeve, rather than a separate piece, is a seamless extension of the body.
The jacket thus has very soft shoulders, with a shape similar to a one-piece raglan sleeve. The only difference is that there's a seam running over and around the shoulder, following a track similar to what you'd see on the (usually) dropped shoulder on an old-fashioned engineer's jacket.
A lining runs halfway down the inside of the engineer jacket, in two great sweeping curved panels. The rest of the jacket on the inside, meanwhile, is neatly finished with cotton binding (apart from the front panel of the jacket, that is, which is actually fully lined, or rather "fully faced", speaking technically).
With things so eventful on the outside of the jacket, there's one simple jetted pocket on the inside. It's on the right side as worn, and positioned quite low down so is very readily accessible.
The cloth is cotton — a classic canvas weave — of middling weight. It is brushed on both sides, and as such, is very agreeable indeed on skin: soft, warm, and inviting. The brushed finish also gives the cloth a subtle nap, which make it softer on the eye, and thus the jacket has an easy "worn-in" look right from the get-go.
