ULTRA BREATHABLE, ULTRA COOL. Light like air. Cool like a breeze. The Nike TechKnit Top uses breathable, sweat-wicking technology to help keep the heat out and let you focus on the road ahead. Its advanced design is geared for movement, so you can fly freely through your stride. This product is made with 100% recycled polyester fibers. Less Sweat, Better Feel: Nike Dri-FIT ADV technology combines moisture-wicking fabric with advanced engineering and features to help you stay dry and comfortable. Minimal seaming gives you a soft, smooth feel. Cool Down In Hot Zones: Breathable knit fabric at the chest, upper back and sleeves helps keep air flowing for a cool feel as you run. We tested real runners (like you) to discover where you heat up the most, helping us place ventilation in key zones. The Look of a Classic: The top's knit structure forms the iconic Nike chevron at the front, nodding to the look of the Windrunner jacket from 1978. Product Details: 100% polyester. Machine wash. Imported. Not intended for use as Personal Protective Equipment (PPE).
