The NuMetrex Cardio Shirt for men was designed to provide an alternative to cumbersome heart rate monitoring chest straps that can chafe, slip and loosen during workouts. Constructed of an advanced wicking fabric with special sensory fibres integrated directly into the garment, the shirt is said to allow men to wear a heart rate monitor without knowing it is there. The conductive fabric moves with the body, picking up the heart’s pulse and sending it to a compatible watch or cardio machine via a transmitter that is snapped into a pocket on the shirt.

Another new addition, the NuMetrex Heart Sensing Racer Tank, is said offer the same seamless monitoring capabilities as the NuMetrex Heart Sensing Sports Bra, which was introduced in 2005, but features a shelf bra where the electronic sensing technology is integrated into the fabric to monitor heart rate. It is made of quick drying nylon Lycra with a second-skin fit that offers medium support.
