What it is

A soft fabric band worn on the upper arm at night, holding a small sensor that records sleep stages, heart rate, heart rate variability, blood oxygen, breathing and skin temperature. Results show in the Garmin Connect app. It has a vibrating smart-wake alarm. The sensor pops out so the band can go in the washing machine. It comes in two band sizes.
