The Numetrex Bra is the latest way to get all hot and sweaty effectively. Basically, it has a heart sensor built into the fabric - yes, the fabric!

Yep, that makes it incredibly comfortable.

The NuMetrex™ Heart Rate Monitoring Sports Bra uses unique textiles to sense and respond to the body. Our new bra is designed to give women the option to wear a strapless heart rate monitor. Now there’s a direct link between your body and the training information you need to reach your goals. The NuMetrex Heart Rate Monitoring Sports Bra works with the Polar WearLink™ Transmitter and compatible* watches. It also connects with most fitness machines like spinning bikes and elliptical trainers with integrated monitoring devices. - Numetrex Bra
