Can anyone recommend a heart rate monitor with the most comfortable strap? I've tried Polar and Nike, but they press and bruise my sternum. I've tried different solutions to alleviate the problem (strap below sternum, cotton wool), but then the signal may not get picked up/or be inaccurate. I end up not even using the HRMs (but I'd like to). The strapless monitors look like they're not accurate.
So if anyone has a recommendation, I'd appreciate it.
