What Our Gearhead(R) Experts Are Saying: "This is one of my favorite layering pieces because it's ridiculously soft and stretchy but still looks put together. The stretch twill moves easily, so it's comfortable for all-day wear, and it works as a light jacket over a tee or as a midlayer under a coat." We're big fans of layers that work nearly year-round, and the Marine Layer Pacifica Stretch Shirt does just that. Made with a stretch twill fabric, this overshirt combines the look of structured cotton with the comfort of a sweatshirt, giving us a polished style that doesn't sacrifice ease of movement. With a soft hand feel and flexible stretch, it's perfect for wearing over a tee on cool fall mornings, layered under a jacket in winter, or solo on spring days. Its classic fit keeps it versatile and easy to style, making it a go-to piece that earns a place in our rotation season after season.
