Elomi EL8042 Energise Underwire Sports Bra with J Hook Navy Geo 36GG This geometric print sports bra gives taller coverage at center and sides, with minimal stretch to deliver support and bounce control without squeezing or discomfort. Made of polyester, nylon and elastane. Multipart, unlined (unpadded) underwire cup has an integrated side support panel that is lined with fine mesh for more powerful control. Non-stretch simplex cup panels wick away moisture and offer consistent shape and support that keeps you contained. Non-compression design separates breasts, shapes and supports. Sewn-on elastic along neckline edge sustains fit. Center - tall, narrow arched center panel. Sewn-on foldover elastic along bottom front offers a comfy fit without chafing. Tall sides and back are supportive microfiber with fine mesh lining, and have sewn-on elastic at top and bottom edges. Flexible back construction makes an easier conversion to a racerback with a movable coated metal J-hook (using lengthened straps). Wide, center-pull, restricted stretch elastic straps are soft and adjust at back with coated metal hardware. Hook-and-eye closure has soft lining and secures at back with coated metal hardware.
