Lightweight with double ripstop construction, this vest is made with a nylon Pro-Meteo 1 layer Airtastic™ fabric for enhanced durability and windproof performance. The durable water repellent treatment repels moisture to keep you dry in light rain showers. Microfresh mesh side and back panels keep you cool while fighting off odours on long summer runs. The stretch polyester and elasticated arm holes let you move freely. You can securely store small items in the quick-access front and back zipped pockets as well as the open back pocket. Designed with functionality in mind, the Shadow Vest for men easily packs down when not in use without taking up essential space.
