The Nike men's Therma Essential Running Pants are built thicker to keep you up and running during the winter months. Ideal for layering, they are easy to put on and feel super soft on the inside. Warm knit fabric is medium weight and brushed on the inside for a super-cozy feel. Pants fit standard through the upper legs and taper to a slim fit towards the ankles. Zippers at the ankles make the pants easy to put on and take off. Sweat-wicking technology helps you stay dry and comfortable.
