4iiii's chest-strap heart rate monitor. It runs more than 540 hours on its battery and is sealed to IPX7, so sweat and rain are part of the job.
Paired with a 4iiii power meter, it puts your heart rate next to your watts, which shows how hard an effort really was and how quickly you recover from it.
