The Nike Run Division Men's Long-Sleeve Running Top combines the casual look of a tee with tight-fitting long sleeves for the performance you need during your workout. Its outer top has a standard fit, which follows the shape of your body with added room to help you move freely. As part of the Nike Run Division collection, this style combines two looks with the ease of just one shirt. Soft and Sweat Wicking The soft fabric has a bit of wool for softness and warmth. Dri-FIT Technology helps keep you dry and comfortable by wicking sweat away from your skin to the fabric's surface, where it quickly evaporates. Breathe Easy A mesh back lets body heat escape and air flow, so you can stay cool and comfortable throughout, and beyond, your run. 2-in-1 Comfort Long, compressive sleeves provide support and a snug feel, while the tee-like top layer has a standard fit for pre- and post-run comfort.
