Running, hiking, or a brisk morning walk – the lightweight Climate Shirt keeps off the chill and wicks away sweat. Zip-up storage The quarter zip closure at the front means it's easy on, easy off – because nothing should get in the way of your performance. And that goes for your storage too, with a discreet drop-in side pocket with zip to store your card and other essentials. Cold-weather protection It's all in the details. So we've added a thumb hole for all-over coverage. Plus, reflective elements for low-light safety. And it’s made from fully recycled, breathable polyester that wicks moisture faster than most running shirts. Warm in the cold, cool in the heat – the perfect balance. Ultra-stretch fabric Made for long-haul runners and all-day trekkers, the four-way stretch powers your every movement without restriction. And darts located at the elbow and back allow the shirt to seamlessly curve and contour to your body.
