You'll love the functional sporty style of this sports bra, with superior support and built-in sweat wicking properties. Made from polyamide, polyester, and elastane. Encapsulation styling envelops and surrounds the breasts to prevent the "uni-boob" look. Cup overlay has curved, angled seams to increase support and shape the bust. Neckline edge has sewn-on elastic to prevent spillover. Center - tall, narrow center panel for more coverage. Wide, soft sewn-on elastic underband has a ribbed, non-slip interior to ensure a secure fit. Tall sides and back have a powermesh lining to maximize support and coverage. Wide front straps reduce the pressure on your shoulders while the elastic back straps adjust with plastic hardware. Center-pull straps have convertible plastic clasps at the rear bases that allow for conversion into a crossback style. Additional restricted stretch elastic extends from the convertible hardware and down the side for a stronger hold. Padded hook-and-eye closure at back. See Fitter's Comments below for hook count. Designed with high quality microfiber that absorbs moisture and dries quickly to prevent unwanted clinging.
