The Nike Pro Hyperwarm Shield fitted men’s shirt offers the ultimate warmth and weather protection. Locking in heat with 3-D thermal knit fabric panels, the shirt repels wind and rain making it perfect for the unpredictable winter weather. Moisture-wicking, Dri-FIT Max fabric reduces discomfort and eliminates chill during intense periods, while Nike Shield technology keeps you dry and comfortable.

Nike Women
