Product Info

The Obermeyer Cosima Down Jacket combines the portability and light feel of a down jacket with the versatility of strategically mapped synthetic insulation for a go-everywhere winter coat that performs in variable conditions. It boasts 15K protection to keep the elements away from your inner layers, vents to help regulate body temperature when working up a sweat, and a powder skirt to seal out the cold and wet on the deeper days. It also has ample pocket storage for your essentials and classic athletic style.
