The Victoria's Secret On Point Sweat Knockout Front-Zip Sport Bra in black is a high-performance, maximum-support bra designed for high-impact activities like running, HIIT, and boxing. It is famously recognized for its "bra-within-a-bra" technology, which provides a double layer of security and bounce control. Core Features & Design Dual Closure System: This bra features a patented design where an inner layer with cushioned underwire cups clips together in the center, while an outer layer zips closed for additional compression. Auto-Lock Zipper: The front zipper is designed to "click" and lock into place, preventing it from sliding down during intense movement. Maximum Support: Built with flexible underwire cups and a racerback or crossback strap design to provide powerful bounce control and stability. Moisture Management: Constructed with TurboWick® or Body-Wick liners, the fabric is moisture-wicking and quick-drying to keep you cool during heavy sweating. Comfort Details: Includes adjustable, padded straps to reduce shoulder pressure and smooth, bonded no-seam edges to prevent chafing. Feel free to ask any questions Smoke and pet free home
