Take most outerwear on a run, work up a good sweat, and you’ll be wearing soggy dead weight in short order. The Outer Limit™ vest is designed to get around all that. The main body is made from a lightweight, highly flexible fabric that efficiently wicks sweat – no heating up and then bogging down. A hit of insulation through the shoulders gives you enough wind- and chill-cutting warmth for the start of a workout and won’t have you overheating at the end. Reflective trim on all sides keeps you seen when running roadside at dusk. And when you’re out enjoying nature at slower pace, it makes an excellent mid layer for your cold-weather kit.
