The Award-Winning REFLECT360 Cycling Jacket is the world's first to be designed using a 100% reflective outer-shell. The globally best-selling jacket's high-quality material is designed to look and feel great while keeping the weather out. The reflective capability of the material helps other road users to identify a cyclist's position on the road at night, giving them extra time to react and maneuver appropriately. The REFLECT360 jacket incorporates multiple vents—front, shoulder/back, and underarm. This allows the user to regulate body temperature. By opening the front zipper vents a "through-flow" is achieved. The air enters the front vents, cools the body, and exits via the shoulder/back vents. During the winter, the vents can be closed and are designed to also be used as extra pockets, if required. These features enable the jacket to be used all year round. The jacket also has an inside chest pocket and a large lower back pocket to store any extra layers or a map. About the fabric: The fabric used for the REFLECT360 range is highly technical. During daylight, it is a modest grey color. At night, when the fabric picks up an external light source, e.g. vehicle headlights, it gives "astonishing reflectivity" (quote: Cycling Active Magazine).
