Crisp leaves on the ground, background music provided by football games on TV. It's too cold for a full-on jacket, it's too warm to don your winter coat, you know what time it is: shacket o'clock. The SLVDR Pilot Shirt Jacket fits the bill in a thick cotton twill, with just enough stretch to keep from feeling like one of those work shirts that can stand up on their own. With handwarmer pockets and a nice collar, it's ready for all your shoulder season activities.
