Breathable 20mm silicone sport watch strap (Polar & Withings compatible) – breathable elastic replacement band
Product description
Quick overview
A breathable silicone replacement strap can sound like a small upgrade, but on sweaty days it’s the difference between “fine” and “why am I wearing this?”. This 20mm sport band is designed to swap onto several Polar and Withings models, with a breathable, elastic silicone build that’s meant to feel lighter and dry quicker than a solid, non-vented strap.
If you’re buying a replacement band, the main things to get right are compatibility and comfort. On paper, this one focuses on airflow (lots of breathing holes), washable everyday wear, and an adjustable metal buckle. It’s also available in a couple of colour combinations, so you can match it to outfits rather than living with the same look every day.
It’s not perfect, though: the strap is specifically listed for certain model sizes and it explicitly excludes a few variants, so you’ll want to double-check you’ve got the correct watch model and case size before ordering.
Where it stands out in everyday use
The strap’s breathable elastic silicone design is the headline. Instead of a flat, non-vented band, it uses many breathing holes, which should help reduce that clammy feeling when you’re commuting, training, or just wearing it through a long day.
It’s also described as soft, flexible and lightweight, which matters more than people expect if you wear your watch for hours at a time. The quick-drying and washable angle is particularly practical if you sweat a lot or you’d rather rinse and re-wear than wait for a strap to dry out.
A small use example
Imagine you finish a gym session and your current strap is still damp. With a washable, quick-drying sport strap like this, you can rinse it after use and get back to normal sooner. It’s a straightforward “keep it wearable” approach for active days.
Comfort, fit and the buckle
This is a 20mm band with a stainless steel buckle and a freely adjustable fit. That’s helpful if your wrist size sits somewhere awkward between common sizes, or if you prefer a looser feel when working out.
The band being flexible and breathable is also aimed at long-wear comfort. Still, do keep expectations realistic: “breathable” can make a noticeable difference, but it won’t magically turn a watch into a sweat-free device. If you’re very sensitive to skin irritation from silicone, it’s worth being cautious with any replacement strap.
Compatibility to check before you buy
Compatibility is the biggest purchase risk with straps like this, because the listing clearly narrows what it does and doesn’t fit.
Based on the information provided, it’s compatible with: - Polar ignite, Polar ignite 2, Polar ignite 3, Polar Unite, Polar Pacer (but NOT Polar Pacer Pro) - Withings ScanWatch 2 42mm and Withings ScanWatch 42mm - Withings Steel HR 40mm and Withings Steel HR Sport
It is explicitly listed as NOT compatible with: - Withings ScanWatch 2 38mm and Withings ScanWatch 38mm - Withings Steel HR 36mm
So, if you’re unsure about the exact model variant or case size, take a moment to confirm it first. Buying the wrong width/size is the easiest way to end up with a strap that simply won’t mount properly.
What you’ll notice from the materials and build
The strap is made from silicone described as high quality, soft and flexible, and it’s designed to be washable and easy to clean.
In terms of how it feels, the combination of breathable holes and elastic flexibility is clearly meant to improve comfort and reduce that “stuck to your skin” sensation that can happen with some bands after sweat.
Who it suits (and who should look elsewhere)
It’s a good fit if you want a sport-style replacement band that’s built around breathability, quick drying, and straightforward cleaning. It also makes sense if you’re trying to refresh your smart watch look without buying a whole new device.
It may not be the best choice if you need it for one of the explicitly excluded models (for example certain 38mm or 36mm Withings variants), or if you prefer a strap style that isn’t silicone.
Also, it sits more in the “practical everyday replacement” category than a premium, fashion-first strap. If you’re specifically trying to “upgrade” comfort beyond what your original band already offers, you may find it improves things, but it won’t necessarily feel radically different.
Pros
- Breathable elastic silicone with many breathing holes
- Soft, flexible, lightweight feel for daily wear
- Washable, quick drying and easy to clean
- Adjustable stainless steel buckle for a tailored fit
- Colour combinations available to suit different outfits
Final verdict
When it makes sense, this breathable 20mm sport strap is a sensible replacement if you own one of the listed compatible Polar or Withings models and you want a more comfortable, washable strap for active days.
You may want to skip it if your watch is one of the excluded variants, or if you’re not ready to double-check the exact model and size. For anyone with the right match, it’s the kind of straightforward swap that can make your watch feel easier to wear—especially when you sweat.
