Dual Enhancement The 2(X)IST lift collection boosts your package, your butt and your confidence! With two special elements added to enhance your body. In the front is an elastic mesh support hidden behind the contour pouch that lifts and boosts the goods. The mesh keeps the fit flexible and breathable, so it's never uncomfortable or binding. In the back are two hidden lifting straps that are actually part of the undies construction, so the only thing you see is a butt that looks great.
