Made from a lightweight poly knit fabric and cut in an athletic fit, the New Balance Women's Impact Short Sleeve Top gives an airy feeling and sits comfortably against your skin without feeling restrictive. The mesh blocking provides excellent breathability, allowing air to penetrate the fabric and circulate around, dispersing heat so you stay cool and well-ventilated. NB Dry X delivers premium moisture management, keeping you dry throughout the toughest workouts by drawing sweat away from your skin, while NB Ice X technology dries extremely quickly so you are always free from distraction and focused on your training.
