Polar Pro Chest Strap - Heart Rate Monitor Belt

Decent chest strap, nice tight fittings for the monitor. It is comfortable to wear and with regular cleaning (in the shower, not washing machine) has worked faultlessly (Dec 2025) since its first use (March 2025). Double check the size, they tend to be on the small side.

great replacement for a tired strap

Comfort fabulous - fits well, no seams or raised areas to chafe. No irritation from plastics used. Clasp is excellent. Easy to use and secure Hr measurement reliability in use is great. It is consumable / textile - so lasts in proportion to use and care... Wash in accordance to instructions, as harsh washes accelerate wear. Pull the H10 off with care so poppers stay bonded. These will help extend life. I do wish polar would look into durability - other straps do last much longer (although don't read as reliably or fit so easily and comfortably)..

I bought this strap to replace the strap from my Garmin HRM run. The module from my Garmin fits into this strap fine (see first two photos). The space between the 2 metal connectors must be ever so slightly smaller on the garmin as the polar belt has a very tiny kink in it which can be seen in the second photo. This has absolutely no impact on its effectiveness and can’t be felt at all while wearing it. The problem I had with the Garmin strap is that it would show a very high heart rate between the 2-3 and 9-10 minute mark and then drop down to a normal reading. It would also suffer from spikes in heart rate that were far higher than my max heart rate. You can see these on the third photo. With the Polar strap I’ve had none of these issues. Consistent heart rate readings the increase and decrease as expected with me perceived effort. I’m about 10 runs in now and it’s been rock solid throughout. Can’t complain.

Having gone through numerous replacement straps for a Garmin HRM, this one definitely seems the best. Sturdy and comfortable to wear this strap appears not to suffer the drop outs or inaccurate readings of cheaper options (including the official Garmin offering). Technically, it's not a perfect match for the Garmin sensor but it does fit and definitely works. Watch out for sizing though. You'll probably need a bigger one than you think. I'd normally think that 2XL would be far too big so I thought "M to 2XL" would definitely fit someone that needs Castelli XL or Endura L. But no, this one is only just big enough. P.S. Thanks for the tip "DC Rainmaker. com" (all one word)!

The easy-release fastening on this belt makes it worth buying. It also inspires confidence that it is made by a brand with long experience in sports metrics.

Comfortable and easy to wash. Move the buckle so you can reach it easy when tired after workout. They come in different sizes and colours. Its hard to see how it could be improved.

Was having some haywire readings on the hrm : sub-100 bpm readings are fine :) , but am not particularly convinced by sub-40 & sub-30 bpm ones (!!). Changed battery in (h10) hrm unit first, without any improvement. Time (for me) to swap out the not-yet-three-years-old h10 strap, next. Opted for the Polar Pro strap which is very nice and has worked flawlessly today, although an old Garmin strap (still with h10 unit) did the job for a few days, whilst waiting for the replacement to arrive. ’Many thanks’ to Amazon for organising delivery of a second strap, after I initially received a size I hadn’t ordered (these things happen) ; much appreciated.

works well and is durable too

Perfect fit. Works well

価格の安い中華物も出回っていますが、肌に直接つけるものなので純正品を選んでいます。モチベーションを上げる的なものです。安いものでもよほど品質が悪くなければちゃんと心拍はとれますから、消耗品と思えばそっちでもいいのでしょうけど、私は30年以上Polar製品ばかり使ってきてるので、メーカーを応援するためにも純正品を買うようにしています。 お値段は少々高いですけど、細かい部分の作りや素材はいいですよ。毎日2〜3時間使っても手洗い、タオルで軽く脱水、陰干しをこころがければ1年は持ちますから、本気で運動している方なら許容範囲の価格だと思います。

El producto funciona muy bien, compré solamente la banda y funcionó perfectamente con el pulsometro de la misma marca que ya tenia, lo he usado por meses y funciona muy bien, tal como lo esperaba.
