The Classic Waterproof Running Gilet is a new lightweight gilet that has high rates of breathability and waterproofing that will help keep you warm when out for your run during those times when a little extra layer will help keep your body warm but you don't need a full jacket, or in winter when an extra layer is needed. We've used a large amount of reflective detailing to ensure good reflectivity at night. Manufactured using a blend of four-way stretch fabrics that combine to give you a high-spec flexible gilet that has sealed sewing lines (seam-sealed) to ensure no water gets in. Incorporating high levels of waterproofing (20k) and breathability (20k), and yet with a weight of only 200 grams, performance is at the forefront of the design.
