The Vigor Vest is a lightweight, water-resistant top layer that's ideal for moderate weather protection as well as temperature regulation. It'll keep you dry when the forecast gets gloomy, but is breathable enough to keep you from heating up as the miles go by. The vest also features a safety-first reflective design on the chest and back panels, helping to announce your presence to cyclists and drivers on dark early-morning and evening runs. In addition to full zip hand pockets, one turns into a self-storage front pocket. It's got an elastic strap, for easy carrying in hand, or on your arm for hands-free movement, when the sun comes out.
