The Nike Dri-FIT Superset Top feels smooth and nonrestrictive as you push, pull and lift with a design that shifts the shoulder seams out of the way. Breathable fabric helps you stay cool. Lightweight, breathable fabric with Dri-FIT technology moves sweat from your skin to help keep you cool, dry and comfortable. Hem vents at the sides and redesigned sleeve seams help you move without restrictions as you stretch, lift and sprint. A high collar and a slightly longer back help keep you covered as you move through your workout. 100% polyester.
