Vests are a runner’s best friend when the weather isn't quite cool enough for a jacket. That's why we've taken the high-tech, waterproof yet breathable technology of our Say Anything Jacket and put it into a vest that'll keep your core dry while your arms fly free. It all starts with a five-star fabric; in this case from the scientists at Schoeller, a global leader in high performance, technical fabrics. As a 2.5 layered laminate, Schoeller's -ecorepel® is designed specifically for high intensity output in high intensity weather. As you heat up, the textured interior keeps the fabric from sticking to your skin, while the specially designed laminate exterior reduces surface tension and allows water droplets to quickly roll away. We've sealed the deal, quite literally, with 100% waterproof zippers. Finishing touches include a stand-up collar and two secure, waterproof zip pockets for storing the essentials.
