Nike New York Slam Polo Fall 2021 Men's Tennis Apparel White/Binary Blue/University Red : Crafted with innovative materials, the Nike New York Slam Polo Fall 2021 performs at the highest levels of play. The cutting-edge design uses data from heat maps to add breathability and stretch where you need them the most. The reshaped sleeve design lets you swing, serve and hit overheads without worrying about fabric bunching or feeling restrictive across your shoulders. Nike Dri-FIT ADV technology combines moisture-wicking fabric with advanced engineering and features to help you stay dry and comfortable. Heat and sweat maps determine where you need more breathability and stretch, then incorporate the zones into fabric made from 100% recycled polyester fibers. Nike used athlete insights to create a sleeve shape for tennis. The update moves seams from the top of your shoulders to the front, letting you swing, serve and hit overheads without worrying about fabric bunching or feeling restrictive across your shoulders. Contrast seam colors, a ribbed collar and a NikeCourt patch create a classic look. Stripes on the cuffs and collar add heritage style.
