The Björn Ace Women’s Pocket Ribbed Tennis Tank in dark blue brings together a clean, modern look and practical functionality for on-court play. The ribbed fabric, made from recycled polyamide with added stretch, adapts to your movements and maintains a close, slim fit that follows your shape. A classic round neckline is combined with a wider racerback cut that allows full freedom throughout every swing. In addition, the integrated pocket at the lower back offers convenient storage for balls during rallies.
