I bought a Polar F11 HRM and I liked having the calories burned, HR data etc...but I found that the chest strap, adjusted to the largest size, was a bit tight. I could get it on, but there was enough tension to make it annoying.
I have a 48 inch chest...I wear 3XL jerseys. Anybody know if the Nike or Timex or any brand HRMs with a more Clyde friendly chest strap???
