The Nike Dri-FIT One Tank is our most versatile top, designed for all the ways you work out—from the machines to the mat to the kilometres. Soft, smooth fabric (made from 100% recycled polyester fibres) comes in a breathable silhouette to keep you cool and dry. Sweat it Out The breathable design with Nike Dri-FIT Technology moves sweat away from your body for quicker evaporation, helping you stay dry and cool. Move in Comfort Soft, smooth fabric curves down at the back hem for a little more coverage. Small side slits create extra give while you move. Look Your Best Not too tight or too loose, the design highlights your natural shape without feeling restrictive.
