A trench raincoat is a long, belted rain coat cut to shed water while you keep walking, and Duck Apparel makes two of them for the Australian market, The Regent Trench and The Landmark Trench. Both sit on the rain side of the Duck Apparel range rather than the down side, so they are chosen for wet and windy days rather than for the coldest mornings of the year. This page explains what the shape actually does, how to compare the two trenches, and how to decide between a trench raincoat and an insulated coat in Australia.
