The raglan sleeve is what separates this coat from every squared-off overcoat on the rail. The seam runs from the underarm to the neck instead of cutting across the shoulder, so the line stays soft and the coat moves with you rather than sitting on top of you. Over a jumper it never bunches at the shoulder, which is the usual complaint with a coat this long.

The surface is brushed, with a faint nap that catches the light and gives the deep dark brown some depth on a grey day. A wide notch lapel opens across the chest, the double breasted front closes high against the wind, and the self-tie belt threads through rear loops so you can draw the waist in or leave it hanging and let the coat fall straight. Side pockets are deep enough for gloves and a phone.

It falls below the knee, which covers a dress or full length trousers properly through the coldest months. Our model is 5'9" and wears a size S. Sizes run S to 2XL in Dark Brown, cut loose with room to layer, so take your usual size. Hand wash it or have it professionally dry cleaned, and hang it on a broad hanger so the shoulders keep their line.
