Don't be afraid to exercise when the cold sets in. The Nike Pro Warm collection lets you stay on top of your game, even in the coldest weather. This long-sleeved top is made from soft, stretchy fleece fabric, with breathable inserts for maximum comfort while you practice your favorite sports and activities. Our design team added a rounded hem for two reasons: it guarantees extra protection, or a secure fit when you wear the top tucked into your pants. Sweat-wicking Nike Dri-FIT technology for enhanced evaporation rapide. You stay dry and enjoy total comfort. Lightly stretchable fleece fabric conforms to your body for added softness and warmth. Mesh inserts in the back and under the arms provide extra ventilation for targeted cooling. The rounded hem gives you optimum protection before and after training, to accompany all your multidirectional stretching. The extra length also keeps the top tucked into the bottom.
