The Index Sleep Monitor is an upper-arm band designed to record up to a week of sleep and feed data into Garmin Connect. The band is 2.5 inches wide and comes in S/M and L/XL sizes to fit different upper arm circumferences. The band weight ranges from 16 to 20 grams, while the removable module weighs 14.5 grams and charges with a standard Garmin cable. Garmin advertises up to seven nights of tracking assuming eight hours per night, and reported battery performance matched that expectation. The monitor can be used without a Garmin watch but then requires the smartphone app to view detailed sleep data.
