Stay comfy and cozy during your cold runs with Nike Therma-FIT Element Half-Zip. Not only does this shirt keep you warm with its Therma-Fit technology, but it even has built-in mittens! The heat-managing fabric with Swoosh-shaped nodes will help keep you warm during even the coldest runs by keeping your body heat in and wicking away any sweat. Mitten cuffs with thumbholes extend from the sleeves to help keep your hands warm. Each sleeve also has a foldover elastic band around the cuff to secure the mittens when not in use. So you can wear it three ways - cuffed, with thumbholes or as mittens. This half-zip is made with at least 75% recycled polyester fabric, with elements of spandex added to help you move freely. There is also a zippered pocket on the left side to stash some cash or a key. Plus, with its relaxed fit, you can wear this shirt on its own or use it as a layering piece. Enjoy those cold winter runs in the Nike Therma-Fit Element Half-Zip. Looking for other cold weather running apparel? Check out our guide on the best winter running apparel.
