This bib is compatible with the original Protern Sensor only. For the new Live sensor, see the Protern Bib (Live).
The Protern Bib keeps the Protern Sensor secure on your back and in view of the satellites. We recommend wearing it as the outermost layer for the best accuracy.
Protern Sensor not included.
Sizing
Below are guidelines for sizing. Larger is generally better as the bib can fit over a jacket. If the athlete will wear the sensor in a race, it is possible to use double-sided tape and attach it directly to the back protector under the race suit.
- Extra Small - Fits the smallest athletes
- Small - Fits a U12 athlete over a race suit
- Medium - U14 over a race suit
- Large - U12 and U14 over a jacket, U16-U18 over a race suit
- Extra Large - Fits everyone over a jacket, fits larger U16 athletes over a race suit
