Another great addition to our shacket family, the Polar Fleece Shacket is thick and warm, with a smooth and soft fleece outer and a brushed back inside. This thick shirt can be worn on its own, but is ideal as an overshirt, teaming well with a T-Shirt or fine knit. With all the styling of a jacket, this can take you through all the seasons, just add more layers as the temperatures dip. Weird Fish Men's Boyd Plain Polar Fleece Shirt in Navy Size: Medium
