Men's Trench Coats: A UK Buying Guide

For a British autumn and spring, choose a double-breasted trench that ends just above the knee, with a storm flap, a belt you can actually fasten, and room for knitwear underneath. It is a shower-and-wind coat, not a waterproof. WARDLEY's Embankment is £278.00 in Stone, Navy and Black, sizes S–XXL.

The trench is the coat men reach for when the weather cannot make up its mind: too warm for the winter overcoat, too wet and too windy for a jacket. It is also the coat most often bought wrong — bought as a fashion shape rather than a working one, in a length that fights the wearer's height, or in the belief that it will keep out real rain. This guide separates the pattern from the marketing: what makes a trench a trench, how long it should be, how it should fit, what it will and will not do in British weather, and where it sits against the overcoat you may already own. It finishes with the one trench in our own range, described exactly as its product page describes it.

What makes a trench coat a trench coat?

The pattern was settled a century ago, for officers in the First World War, and it has survived because every detail earns its place. A trench is double-breasted, which wraps the chest in two layers of cloth against the wind. Across the back and chest sits the storm flap, a loose panel that sheds water off the shoulders instead of letting it soak through the closure. The epaulettes were for rank insignia; today they stop a bag strap sliding off the shoulder. The belt is not decoration: fastened, it closes the coat against the wind and gives the shape its waist; the cuffs are belted for the same reason, to seal the sleeve. A coat missing most of these is a long jacket in a trench colour. A coat with them is a tool, and it is the details — not the shade of beige — that you are paying for.

Is a trench coat waterproof?

Traditionally, no — and it is better to know it before you buy than at a bus stop in November. The classic trench cloth was densely woven to resist showers and shed a short walk in the rain; it was never a waterproof in the way a sealed raincoat is. Our Embankment states it plainly on its page: it is a lightweight trench for showers and wind, not a waterproof coat. That honesty defines its season. From September to November and again from March to May, it is the right weight for most days — over a jumper, against the wind, through a shower. In sustained rain, or in the cold weeks either side of Christmas, you want a different coat: our complete guide to men's overcoats works through the heavier end of the rail.

How long should a trench coat be?

Just above the knee is the classic answer, and it is the length our Embankment is cut to: 86cm in size S rising to 94cm in XXL. Shorter than that and the coat loses its weather coverage and its line; longer and it becomes a different garment — a raincoat-overcoat hybrid that can swamp a shorter frame. The proportions matter more than the number: the hem should clear the knee so the coat moves when you walk and sits cleanly when you sit, and the belt should land at your natural waist, not at your hips. If you are between the conventional bands, our guide to how long a men's coat should be sets out the landmark rules that apply to trenches as much as overcoats.

How should a trench coat fit?

Over whatever you wear beneath it — which in Britain usually means knitwear. A trench that fits perfectly over a shirt will pull at the buttons over a roll neck, so judge it dressed as you will actually wear it. Our Embankment is a regular fit with room for a knit underneath; its chest measures 103cm in S to 118cm in XXL, and the advice on its page is the advice we would give in person: between sizes, take the larger. The shoulders should sit at your own shoulders, the double-breasted front should fasten without strain across the chest, and you should be able to raise your arms and sit down belted without the coat rearranging itself. Measure a coat you own that fits and compare — every product page of ours publishes its garment measurements for exactly this purpose.

What do you wear with a trench coat?

Two ways, both shown on the Embankment's page. Belted and fastened over a roll neck, it is a finished outfit on its own — the most dressed a man can look in under a minute. Open over a jumper and shirt, it is a frame rather than a statement, and the jumper does the talking. The colours divide the work cleanly. Stone is the classic trench colour, the one the pattern was drawn in, and the easiest against navy and charcoal trousers. Navy is the sharper city option, darker against the rain and better after dark. Black works over tailoring, where the other two can look a degree too country. With any of them: charcoal trousers and leather shoes are the reliable ground, and a scarf on the cold mornings the season still produces.

Trench coat or overcoat — and where does the peacoat sit?

Think of the three as a season in coats. The trench is the mid-season coat: light, windproof in effect, shower-ready, at its best from September to November and March to May. The overcoat is the winter coat: heavier cloth, more coverage, made for the weeks when the temperature does the talking — our range runs from the Hampstead longline at £198.00 to the Greenwich double-breasted at £258.00, all compared in the men's overcoats collection. Between and beneath them sits the peacoat, shorter than both, for men who drive and move more than they stand: our companion men's peacoat guide covers it properly. A trench does not replace an overcoat and should not be asked to; what it replaces is the succession of jackets that were never quite right for the weather between seasons.
