You can wear this hybrid style all season long: in the beginning as a layer under your jacket, and, as it gets warmer outside, instead of a jacket. This style is made of a soft, cotton interlock quality with a nylon front. The heat-seal technique gives it a quilted look, but without the stitching. This creates a casual, modern feel, while the black, contrasting details add a cool, sporty touch. The signature Cast Iron details complete the design.
