Mixing underwire with sports bras sounds completely incongruous to me. They just don't go together. This is, however, a new trend in supportive wear for active gals. I wanted to try one out, and Danskin was kind enough to send me its new Aerosilver Flex Sports Bra ($48) for a literal test run.

The bra certainly provides support and reminds me of a 1950s bra updated with a sporty racerback. When I wear it I feel more like I am on the set of Mad Men than running on a treadmill. The bra combines dynamic support with a titanium underwire and compression with molded soft foam cups. The effect feels nothing like the smooshed feel of a regular ol' compression sports bra; this one is actually comfortable. It is made of wicking fabric to maintain dryness and prevent the chaffing. The back of the bra is mesh for added breathability. But I think the most effective cooling element is the thin mesh vent just above the underwire, which not only allows air to flow in to cool you down but it is decorative as well. Unlike most compression bras, the Aerosilver racer back has three closure settings and you can't feel the hardware when you run.

For more details and to view the bra from the back, just read more.
I know the bra is bit expensive, but it holds up well in the laundry and should last a long time. While the bra may cost almost $50, I would say a comfortable, supportive sports bra that makes you look like a woman is priceless. You can find this bra on Danskin's website.
