We worked for two years with the best sports bra designer we know to develop this underwire bra. It's designed to give sports support in a bra comfortable enough to wear all day long. The adjustable straps are inset to eliminate slippage, and the plush-covered underwires never gouge. Plus it aced our washer-dryer durability test. Cups are made of a wicking poly/acrylic. We recommend this bra for women who want both separation and support. By Moving Comfort. Catalog/web only. Only at T9. 32-40 B-DD
