Garmin unveils sleep-tracking armband for nightly use
Garmin just dropped the Index Sleep Monitor—a comfy, screenless armband you wear overnight on your upper arm.
Made from breathable nylon and spandex, it quietly tracks your sleep and syncs all the data straight to your Garmin watch or phone.
Tracks all your sleep metrics
This armband covers all the essentials: sleep duration, stages (light, deep, REM), heart rate, blood oxygen, breathing patterns, skin temperature, and heart rate variability.
There's also menstrual cycle tracking and a gentle vibrating alarm to wake you during light sleep.
It lasts a week on one charge, is machine washable (nice touch), comes in two sizes, and costs $170—no subscription needed.
No hidden fees or add-ons
The Index Sleep Monitor packs in detailed sensors for real insights into your sleep quality and recovery.
Skin temperature tracking is handy for period or illness monitoring.
Unlike rivals like Whoop 5.0 that require subscriptions and extra accessories, Garmin gives you all features upfront—no hidden fees or add-ons—making it a solid pick if you want serious tracking without extra hassle.
