Sports bras have been one of Victoria's secrets for a while, but the latest model, "Incredible" warrants at least a passing mention here at Engadget. It houses sensors and other connected technology within the fabric, courtesy of Finnish smart fabric manufacturer Clothing+ - the same company that has been behind sports tech from the likes of Adidas and Under Armour. The $75 bra comes with the electrodes all built-in, but doesn't contain a heart-rate monitor itself. You'll need to connect that at the back, although the listing doesn't specify which "leading brands" you'll be able to do it with. Alongside the lack of actual heart-rate monitor, there's also no color-changing feature when your similarly-dressed sibling is nearby -- but we're sure customers will cope.
