The piece is made with a face fabric of 81.6% nylon and 18.4% spandex, giving it a lightweight, stretchy feel that moves with you. The cup lining uses the same 81.6% nylon and 18.4% spandex blend, while the side-wing lining is 59.4% nylon and 40.6% spandex for extra stretch and hold. The thin molded cups and mesh side panels keep the piece breathable and cool, making it ideal for lightweight summer wear and a seamless, invisible look under clothes. The fabric is treated for antibacterial performance and is designed for a push-up, side-lifting fit with a W-shaped support frame and adjustable straps.
