Cycling Weekly Verdict

The Garmin HRM-FIT is designed to minimize chafing that a traditional around-the-chest heart rate monitor (HRM) can cause when tucked under the elastic chest band of a sports bra. The Garmin HRM-FIT delivers on its promise with a backless strap design that clips onto a sports bra, but its need to be used with very specific sports bra designs and high price tag may counteract some of its benefits.

Those who wear sports bras when they ride know this unique frustration well: fastening your heart rate monitor (HRM) chest strap only to have it dig into your diaphragm and lose its position on the sternum thanks to rubbing from the sports bra’s elastic chest band. 

This can result in spicy chafing marks that linger long after your ride is done and potentially inaccurate heart rate readings if the HRM is jostled out of position - especially if you try to move the HRM to avoid a chafing hot spot.
