New Balance Women's Essential Tank Top, Small, Black. Basic doesn't have to be boring, especially with the New Balance Essential Tank. This simple tank is packed with style, featuring a racerback silhouette with novelty mesh insets and back. Flat lock seams help minimize chafing, so you'll be comfortable whether you're kicking butt at kickboxing or strength training with weights. The reflective NB logo is not only eye-catching at the gym, but also in the dark.
