Garmin has just introduced the New Index Sleep Monitor, a purpose-built sleep tracker designed to bring together comfort, accuracy, and real-world usability.
Unlike traditional wrist wearables, this device is worn on the upper arm, making it less intrusive while you sleep — yet still highly effective.
At the heart of the Index Sleep Monitor is Garmin’s latest Elevate Gen 5 optical sensor, delivering advanced, reliable sleep data throughout the night.
Paired with the Garmin Connect ecosystem, it empowers users to better understand their sleep patterns and make meaningful improvements to their overall wellness.

Unlike traditional wrist-based trackers, the Index Sleep Monitor is worn on the upper arm, prioritizing comfort and accuracy while you sleep.
It comes with Garmin’s most advanced Elevate Gen 5 optical sensor, offering detailed insights into your sleep quality, recovery, and overall health.
Here’s what really stands out: Garmin now sells replacement bands separately for $49.99.
That might sound steep at first, but when you consider the durability and build of these bands — made from a machine-washable blend of 70% Nylon and 30% Spandex — you’re investing in something designed to last.
The Garmin Index Sleep Monitor come in two sizes (S/M and L/XL) and are built to maintain stretch and comfort even after frequent use.
This move is especially helpful for:
- Users who want a backup band while one is in the wash
- Those who need to switch sizes
- Anyone whose band wears out due to extended use or intense nightly wear
A Closer Look: Why This Sleep Band Stands Out
Garmin’s approach with the Index Sleep Monitor isn’t just about data — it’s about delivering a full sleep wellness experience. Here’s what the device tracks while you sleep:
Sleep Score
Wake up to a personalized score (0–100) based on your sleep duration, depth, and stress levels.
Sleep Stages (Light, Deep, REM)
See when your body shifts through each sleep stage and how long you stay in them.
HRV Status
Measure your Heart Rate Variability each night and compare it to your baseline for better insights into stress and recovery.
Pulse Ox & Breathing Variations
Monitor your blood oxygen levels and how your breathing changes through the night — an important factor for those tracking respiratory issues.
Skin Temperature Trends
Subtle changes in skin temperature can reveal signs of overtraining, poor sleep environments, or even illness.
Women’s Health Features
Women can gain better insight into menstrual cycles, ovulation patterns, and pregnancy health using skin temperature trends and Garmin Connect.
Body Battery™ & Stress Tracking
Understand how restful your night was and how much energy you actually regained.
Smart Wake Alarm
Forget the harsh morning jolt — the Index uses your lighter sleep stages to wake you gently within a chosen window.
“Wearing this smart sleep band every night can provide in-depth sleep insights and a more complete picture of fitness and recovery so users can wake up ready to seize the day.”
— Susan Lyman, Garmin VP of Consumer Sales & Marketing
Is the $49.99 Replacement Band Worth It?
It depends on how you value long-term usability and convenience. If you’ve ever had a wearable become uncomfortable or unusable because of a worn-out strap, you’ll appreciate Garmin’s foresight here.
Compared to smartwatch bands, which retail for $29.99–$39.99, the slightly higher price tag reflects the higher-grade material and design for all-night wear.
From a user perspective, this is the kind of update that doesn’t grab headlines — but matters every night. It also means your sleep device won’t become obsolete just because of a stretched-out band.
How It Syncs with the Garmin Ecosystem
The Index Sleep Monitor integrates seamlessly with the Garmin Connect™ app, and it complements other Garmin wearables beautifully.
If you’re someone who removes your watch before bed — whether for comfort or charging — the Index fills in those overnight data gaps, giving you a full-circle view of your health and recovery.
Final Verdict: A Small Addition, a Big Win for Sleep Health
The Index Sleep Monitor was already a compelling option for serious sleep tracking. By adding the ability to swap out the band without needing to repurchase the entire unit, Garmin is showing that user comfort and product longevity truly matter.
For $169.99, the device offers advanced, science-backed sleep data in a form that’s more comfortable than a wrist-worn watch. And now, with washable, replaceable bands, it’s a solution that grows with you — night after night.
