The Nike Pro Tank breathes and wicks sweat to keep you cool and dry as you push through the burn. The stretchy design with mesh down the centre is made from at least 50% recycled polyester fibres and lets you move comfortably from start to finish. Sweat-Wicking and Cool Dri-FIT Technology helps keep you dry, comfortable and moving naturally. Mesh down the centre at the front lets your skin breathe. Stretch and Support The high-stretch design lets you move freely, while a built-in shelf bra feels softly supportive while you move.
