Maximize your workout with the NuMetrex Heart Rate Monitoring Sport Bra, featuring special sensing fibers knit directly into the fabric! This "heart smart" bra senses your pulse and transmits it wirelessly via a snap-in transmitter to a heart rate monitoring watch or heart rate monitor-enabled fitness machine. Now those cumbersome and uncomfortable chest straps won't get in your way to achieving your ultimate fitness goals. Small, Medium or Large.
