We think a great way for you to select the right size coat, is to compare and contrast against a garment you already own and that you know fits you well. Below you will find illustrations of each size making it a little easier to get the right one for you. A couple of good things to note when buying the Atlantic trench, is that the shoulder and chest measurements are the key to selecting the right size. The coat has a gentle swing and the sleeves a generous fit, this is critical to giving you enough movement in this raglan style. All of the Atlantic family coats come with two sized detachable length sleeve straps, so whether you're tall and rangy or a more compact build, the sleeves should fit nicely. And last but not least, we’d advise you not to be tempted to buy a smaller size in order to achieve a slimmer fit through the body as this causes tension through the shoulder. Remember this style is designed to be worn in the city but also for high jinx and great adventures in the countryside too!
