Replacement Heart Rate Soft Strap for Polar H1, H7, H9 & H10 & Garmin HRM-Dual
A hypoallergenic, machine-washable replacement chest strap compatible with Polar H-series and Garmin HRM-Dual transmitters. Available in three sizes at $14.99 each — the most affordable fix for erratic heart rate readings.
Seller's Note: Erratic or spiking heart rate readings during a workout are almost always caused by a worn chest strap — not a failed sensor module. The conductive fabric that contacts your skin degrades from sweat, body oils, and washing over 8–12 months of regular use. At $14.99, replacing the strap is the right first step before spending $79+ on a new monitor. Snap your existing Polar or Garmin HRM-Dual module into this strap and you're back in business.
- Wide multi-brand compatibility Works with Polar H1, H7, H9, H10, and WearLink transmitters, plus Garmin HRM-Dual, Nike Plus, and Wind transmitters — one strap fits most popular ECG monitors.
- Hypoallergenic materials Latex-free fabric and nickel-free stainless steel snap connectors. Safe for athletes with latex sensitivities and common metal allergies.
- Machine washable Detach your transmitter module and toss the strap in the washing machine. Regular washing removes sweat and skin oils that degrade conductivity and signal quality over time.
- Soft, flexible fit Polyamide, polyurethane, and elastane blend stays in place during running, cycling, HIIT, and swimming without chafing or constant readjusting.
- Three sizes — all $14.99 XS/S (22–33″), M/XXL (28–52″), and 3XL (42–77″) chest circumference. All sizes are the same price. Save 21% off the $18.95 MSRP.
- Standard two-snap mount Two standard snap connectors accept Polar H-series, Garmin HRM-Dual, Nike Plus, and Wind transmitter modules. No tools, no adhesives — press and click.
- Fix erratic readings for $14.99 Spiking to 220 bpm at warm-up? Dropping signal mid-run? 8 out of 10 times it's the strap, not the module. Replace the strap first — it's the right diagnostic step before buying a new $79+ sensor.
- Sweat- and water-resistant Designed for use during sweaty workouts and water exposure. Transmitter modules vary by water rating — check your specific module's specifications for swimming use.
- Polar H1, H7, H9, or H10 users whose strap has worn out or is giving erratic readings.
- Garmin HRM-Dual users looking for an affordable replacement strap.
- Athletes with latex sensitivities or nickel allergies needing a hypoallergenic option.
- Anyone who wants to extend the life of their existing transmitter module instead of replacing the whole unit.
- Users who want a backup strap on hand for training continuity.
- You have a Garmin HRM-200, HRM-600, HRM-Pro, or HRM-Run — these use a different connector system.
- You have a Polar OH1 or Polar Verity Sense — these are optical armbands that do not use a chest strap.
- You have a Garmin HRM-Swim or HRM-Tri (older models with a proprietary snap pattern).

Fast recommendation:
- If your existing Polar or Garmin HRM-Dual is giving erratic readings or dropout, choose the HRM USA Replacement Soft Strap first — it's almost always the strap.
- If you want OEM Polar branding on your replacement strap, look for a Polar strap directly.
- If your module is damaged or lost, or you want HRV, session recording, or 30m swim depth, choose the Polar H10.
- If you want 3 simultaneous Bluetooth connections, ANT+, and Garmin ecosystem compatibility, choose the Garmin HRM-Dual.
Summary
The HRM USA Replacement Soft Strap is a practical, cost-effective fix for athletes whose Polar or Garmin HRM-Dual strap has worn out. At $14.99 for all three sizes — with hypoallergenic materials, a machine-washable design, and broad multi-brand compatibility — it's the smartest first step when readings go wrong. Measure your chest before ordering and size up when between sizes.
