For many serious runners, the chest strap is still the accuracy benchmark next to optical wrist sensors. The HRM-Pro Plus is Garmin's premium strap, packing ECG, running dynamics and multisport connectivity. RunMorph cross-checked independent reviews and real-world user feedback to see whether it deserves its spot at the top of the lineup.

The Garmin HRM-Pro Plus is a high-end ECG chest strap built for runners and triathletes who want electrocardiogram accuracy paired with advanced running dynamics (ground contact time, vertical oscillation, stride length). Its multisport versatility (running, cycling, swimming) and triple connectivity (Bluetooth x3 + unlimited ANT+) make it a solid pick if you already own a compatible Garmin watch. The price is steep if you only want heart rate, and one review reports wear on the strap fabric after about a year of heavy use.
Garmin built its chest strap lineup on a simple principle: the higher you go, the more the pod does beyond raw heart rate. The HRM-Pro Plus sits right at the top, just below the more recent HRM 600. It uses electrocardiography (ECG) to capture your heart rhythm more accurately than optical wrist sensors. On top of that, it sends full running dynamics to any compatible Garmin watch: ground contact time, vertical oscillation, stride length and vertical ratio.
It fits into a lineup RunMorph already covers well, between the more basic HRM-Dual and the HRM 600, its direct successor. The Pro Plus is still on sale and widely stocked by retailers. That makes it a smart pick if you want a great features-to-price ratio in the premium segment without paying launch pricing for the latest generation.
RunMorph tip: advanced running dynamics only show up on a compatible Garmin watch (Forerunner, Fenix and Epix series, among others). Check that your watch is compatible before buying this strap, or you'll pay for features you'll never see.

RunMorph cross-referenced an in-depth, months-long review from an independent cycling outlet with feedback from French users collected at a specialist retailer, to weigh lab results against real-world impressions.
On accuracy, the independent review is very positive: the HRM-Pro Plus proved "consistently accurate" across every tested session, with smooth, dropout-free Bluetooth and ANT+ connections, including when paired with a third-party bike computer. The review gives it 9/10 for performance, praising the ECG technology and the one-year battery life. On comfort, the strap material is described as "soft and smooth," clearly better than Garmin's entry-level models, with a flexible tab at the clasp that cuts down on chafing. The pod stays discreet under clothing, with no real discomfort reported even during long sessions.
French user reviews temper that picture somewhat on mid-term durability. Several praise the instant pairing with Fenix and Edge devices, a secure fit and a very handy tool-free battery swap. One user, however, reports the fabric peeling away around the strap after just over a year of use, which eventually skewed some readings. This matches a general rule for high-end textile straps: repeated exposure to sweat and washing wears the material down, whatever the brand.
| Garmin HRM-Pro Plus | Polar H10 | |
|---|---|---|
| Technology | ECG | ECG |
| Connectivity | Bluetooth x3 + unlimited ANT+ | Bluetooth + ANT+ |
| Running dynamics | Yes (compatible Garmin watch) | No |
| Swimming | Yes, 5 ATM | Yes, waterproof |
| Ecosystem | Best with Garmin watches | Works across brands, highly universal |
| Price | ~€155 | ~€90 |
Both straps share the same ECG technology and an equally strong reputation for reliable raw heart rate readings. The difference lies elsewhere: the HRM-Pro Plus only really pays off paired with a compatible Garmin watch that can use its running dynamics, while the Polar H10 aims for universal compatibility at a much lower price. If your setup is already 100% Garmin and you want the advanced metrics, the Pro Plus makes sense. If you switch watch brands regularly or simply want the best raw accuracy for the money, the H10 remains the benchmark.
The HRM-Pro Plus remains a safe bet if you want the best of the Garmin ecosystem without paying for the very latest generation. Its ECG accuracy and multisport versatility make it a serious training tool, as long as you have the compatible watch to pull all the data from it.
The Garmin HRM-Pro Plus delivers on accuracy and versatility, with reliable ECG technology confirmed by independent reviews and comfortable battery life. Still, it's an investment that only fully makes sense paired with a compatible Garmin watch that can use its running dynamics. 8.4/10: an excellent premium strap if you're already in the Garmin ecosystem, less relevant if you just want reliable heart rate at the best price.
