FYISWHO nylon watch strap (20mm) for Amazfit GTS/GTR 42mm and Active series

If you’re looking to refresh the look of an Amazfit watch without overthinking it, a nylon replacement strap is a simple route. The FYISWHO nylon band is designed for a 20mm strap fit and leans into the sports side of things with breathable, washable materials.

That said, compatibility is the main thing to get right here: the listing focuses on many Amazfit models, and it specifically notes it’s not for Amazfit GTR 47mm. So before you buy, double-check your watch model and whether your watch uses a 20mm strap size.

The essentials

This strap is a 20mm replacement made from nylon, aimed at day-to-day wear and training sessions. It’s described as soft, flexible and lightweight, with a breathable, sweat-friendly feel. The material also dries quickly and is easy to clean, which matters if you’re the kind of person who hates wiping down a silicone strap after every gym run.

In use, it’s the kind of band you’ll likely appreciate when you want less “sticky” feel from plastic-like straps, especially in warmer weather or during longer workouts. You get an elastic strap design and a buckle that lets you adjust the length.

Key features that you’ll actually notice

The setup is intended to be easy. The strap uses an elastic replacement approach and the listing states it can be installed and removed in around ten seconds, with no additional tools required. That’s handy if you like switching colours for different outfits, or if you’re planning to keep a spare band ready.

On the material side, the nylon is positioned as non-irritating and less prone to rubbing than plastic-style bands. It’s also quick-drying and washable, so it’s more forgiving when your day gets sweaty or you pick up dust and grime from everyday activities.

There’s also the styling angle: the band comes with multiple bright colours and a stainless steel buckle, so you can match your watch to what you’re wearing.

What it’s best for (and the limits)

It makes sense if you want a breathable sports strap that doesn’t feel heavy on the wrist. If your priority is comfort during training and practical cleaning, this will feel like a sensible upgrade over basic straps that don’t dry as well.

However, it may not suit you if you’re chasing a more premium, structured look, because nylon is a casual fabric and can feel different to leather or metal mesh. Also, if you don’t have a 20mm strap fit, this simply won’t be the right solution.

And keep in mind the compatibility note: it explicitly says it’s not for Amazfit GTR 47mm, even though the strap is listed alongside other models.

Usage tips

If you’re swapping straps regularly, this elastic replacement design is built for that. For a quick change, you typically just need to remove the old band and fit the new one without tools, then adjust the buckle to your wrist size.

A practical micro-use example: after a workout, instead of leaving sweat to linger, you can rinse or wash the strap (as the listing claims it’s washable) and hang it to dry. Because it’s described as quick-drying, it’s less likely to feel “damp and uncomfortable” the next time you put it on.

What to check before buying

Compatibility is the big one. The listing states it’s for a range of Amazfit watches, including Active 2/Active 3, Bip models, GTS 4/GTS 4 Mini/GTS 3/GTS/GTS 2/GTS 2e/GTS 2 Mini, and GTR Mini/GTR 42mm. But it also clearly says it’s not for Amazfit GTR 47mm.

So, make sure your watch model is on the compatible list and that your watch uses a 20mm strap size. If you’re unsure, it’s worth confirming before ordering rather than assuming all Amazfit models share the same fit.

In the box

The listing calls it a replacement strap, but it doesn’t spell out additional items beyond the band itself. So expect it to be the strap you need to swap, rather than a full set of watch accessories.

Should you buy it?

A solid pick if you want a breathable, washable nylon strap for training and everyday wear, and you’ve got an Amazfit watch that matches the stated 20mm strap compatibility (and you’re not using Amazfit GTR 47mm).

You may want to skip it if you’re trying to fit it to the wrong watch size/model, or if your style preference is more formal or metal-like rather than fabric-based.

If value-for-money is your goal and you like the idea of easy strap changes (and different colours), this is the sort of replacement band that can earn its place quickly.
