Panache 5021 Full-Busted Underwire Sports Bra Black 40F This full-busted underwire sports bra has been independently determined to reduce breast bounce by 83%! Whatever your sport, this sport bra provides the ultimate support, encapsulating your breasts rather than compressing them against your chest. Contour underwire cups with light padding offer full-coverage and shape and support the breasts for less bounce. Underwires are encased and padded for comfort. Mesh insert at tall center front and neckline is breathable. Outer performance fabric wicks moisture away, keeping you dry and comfortable. Built on a base with an elastic underband for superior support. Elastic along top and bottom of sides/back for custom fit and comfort. Sides and back are lined with powermesh for back smoothing and great support. Padded shoulder straps are covered with breathable mesh and attach to wide elastic straps that adjust in the back with coated metal hardware. Coated metal J-hook on the back o-rings allows you to convert to a racer back. Kicked-in rear straps help prevent slipping. Coated hook-and-eye back closure with padded back. For hook count, see Fitter's Comments. Available in cup sizes B-J (H cup in this brand is 7 cup sizes larger than a D cup).
