Why are there a range of different belt sizes available for the Equivital system?

The correct sensor belt fit is imperative to ensuring you can record good quality data in all environments. The ECG, and respiratory sensors are integrated into the sensor belt. A correct belt fit ensures you have correct level of contact and positioning of these sensors to provide highly accurate data. 

There are 4 different sizes of the current B6 belts (non-gender specific).
