Adidas miCoach Heart-Rate Monitor and Supernova Sports Bra
Heart-rate monitors are a pretty basic form of wearable tech. They typically consist of the monitor attached to a strap, which goes around your ribcage. But that strap can be annoying and/or unstylish, so Adidas has created a special sports bra that works with its miCoach heart-rate monitor. The monitor fits neatly into that little pocket on the front of the bra. The monitor costs $70 on Adidas's site (it comes with a strap and an iPhone plugin, so you can track your heart rate on your iPhone), and you can pick up the sports bra for $27 on 6PM.com.
