A pea coat (or pea jacket, pilot jacket) is an outer coat, generally of a navy-colored heavy wool, originally worn by sailors of European navies. Pea coats are characterized by broad lapels, double-breasted fronts, often large wooden or metal buttons, and vertical or slash pockets. Although it first appeared in the early 19th century, modern renditions still maintain the original design and composition.
Always in style for the winter, you can pair this piece with a v-neck t-shirt or a turtleneck if things are a little too frosty. It’s also a great homage to military inspired fashion. (Amazing how we bring it all back. You’ll start seeing a pattern, trust me.)
There are a ton of retailers out there that carry these jackets every season, but look for one that will fit you well and will still look good 20 years from now.
My guess is you will probably be using it for a long time.
