A soft-yet-rugged shirt jacket built for year-round wear The sheer versatility of a good shirt jacket is right there in the name—these killer layers excel as a heavy-duty shirt, lightweight jacket, or even a handsome mid-layer. For this addition to Flint and Tinder’s shirt jacket lineup, they took inspiration from Scotland’s Isle of Islay. Only with this one, they upped the ante with durable, abrasion-resistant nylon and plush insulation for added warmth and comfort. An F+T classic purpose-built for softness and style, this is a sharp-looking favorite that will overdeliver anytime, any place.
