The Nike Run Division Tank marks the return of a favorite with all-new materials. Its updated design was made with runner-informed data, helping you stay cool while looking fast. All-new adaptive knit fabric at the back features laser-cut mesh fabric. The mesh opens with movement, allowing more air in to keep you cool where you need it most. Knit fabric with sweat-wicking technology at the front helps you stay dry and comfortable. Athlete-informed data was used when creating the tank, helping designers add ventilation in high-heat areas.
