NIKE DRI-FIT TECH RUNNING TIGHTS The Nike Tech Running Tights feature a zero-distraction fit which means you can focus on your run. The compression fit enhances support whilst being lightweight and an elastic waistband with internal draw-cord gives you an adjustable fit. The low-friction gusset between the legs reduces irritation while lending a comfortable, athletic fit. A handy, zippered back pocket was made for stashing a media player, energy bar or other small items securely. There's even a vapor barrier between skin and pocket to help keep sweat away from pocket contents. Dri-FIT fabric helps you stay dry and comfortable by wicking sweat away from skin to the fabric's surface, where it quickly evaporates. Also featured are Dri-FIT mesh vents behind the high-heat areas of the knees keeping you more comfortable. Reflective strips have also been added to enhance your visibility in low-light conditions.
