The trench coat is one of those rare garments that has earned its place in menswear over about a century of actual use, and yet most versions sold today manage to get something wrong. The belt is usually the problem. Too flimsy and it buckles awkwardly. Too stiff and it never sits right at the waist. When it works, though, a properly belted trench does something almost no other coat can do. It gives structure to whatever is underneath it, reads as considered without trying too hard, and looks equally at home over a suit or over a heavyweight knit and dark denim. We have been paying close attention to proportions, specifically the collar stance, the belt weight relative to the body of the coat, and where the hem falls. The ones we have picked here have all of those things sorted. A good trench is not a trend piece. It is a coat you are still reaching for in fifteen years.
