What’s a shirt jacket? Sometimes known as an overshirt or “shacket,” (but never a “jirt”), the shirt jacket inhabits the subtle middle ground between button-up and outer layer. Shirt jackets are often made with a rugged exterior, like canvas, or something lighter and weatherproof, like ripstop nylon. They’re almost always lightly insulated, which makes them the perfect lightweight outer layer for the transitional weather that comes along with spring and fall. But shirt jackets are universal too — they can be worn under a thicker outer layer during the winter months, but they’re also perfect for enjoying freshly-brewed coffee outdoors on a brisk summer morning (or passing around a flask on a cool evening).
