The Nike Shield Tech Men's 30" Running Tights are made to get you out there. Areas of weather-resistant fabric help keep you warm and focused for miles. A minimal waistband reduces bulk if you wear these tights under sweatpants in between workouts. The upper front has a layer of Nike Shield fabric. This resists the rain and wind that comes at you as you run, helping you stay dry, warm and on top of your game. Behind the knees and on the lower back legs is Nike Power fabric. This provides a range of stretch and support, so you can move freely and power through the demands of every mile. A zippered pocket on the back right has a vapor barrier to help keep sweat off your cards, keys and cash as you run.
