I am on a Epix 51mm and the band is about 15mm bigger than expected. I measured and had to cut part of the band off.
Its a little fiddly getting it though the eyelet now - but serviceable. I remoed the paracord easily as it was catching on things and had become loosish.

I'll probably buy another as the price is so reasonable.

I have many straps for my Fenix 6x pro, mostly silicon which I have found to rub and irritate my skin of late. I got this for a change and to hopefully allow my skin to heal.

This strap attached very easily - the components are all of high quality machined metal.
This design is obviously the result of taking feedback from earlier iterations as they have nylon stitched in places to prevent skin contact with the metal components. The result is a very comfortable strap that I've worn all day and all night and barely even noticed it is there.- From Amazon.

I wear my Garmin Fenix 6X Pro quite a lot, and the worst thing that I personally have never liked is the supplied silicone strap.
I pulls my hairs when I put it on or take off.
When I sweat it is very uncomfortable and sometimes comes loose.
Sometimes when I tighten it, it catches my skin at the buckle and can sometimes be painful AARRGGHH!

So when I put this very nice looking Bandletic strap on for the first time, I immediately realised that the silicone one was never going to be used ever again!
This new strap has transformed my expensive watch into a whole different feel of comfort.

It also looks much better than the silicone strap and for so little money too.
Should have got one of these ages ago.

BRILLIANT!- From Amazon.

This nylon replacement band is compatible with Garmin models like (epix Pro 51 mm, Instinct 2X, Descent Mk3i 51 mm, Tactix 7 Amoled, Fenix 7X pro, Fenix 7X, Fenix 6X Pro, Fenix 6X, Fenix 5x Plus, Fenix 5x, Fenix 3, Fenix 3 HR, Tactix 7 Pro, Descent Mk2i, Descent Mk1, Enduro 2, D2 Delta PX, and Tactix Delta).

I must admit that it looks very nice on the wrist and this orange color perfectly matches my watch as well as most of my clothes.

Installation and changing old strap on this new one takes literally moments.
The M size fits wrist size 6.69"-7.28" (170mm-185mm) but there is also other options to choose.
It's really durable and wear resistant material.

What's included in this package: 1x quick release pin, 1x 26mm strap, and manual.
The material is also very soft to touch, and breathable.

Great quality at all, and price is really reasonable.
I can easily recommended to anyone.- From Amazon.

Easy swap clip on strap, does not come with replacement watch spring bars as some other straps I've bought have.

Seems nicely made and of high quality materials and is well presented in a branded box. All the stiching looks good. Goes well with the style of the Garmin Fenix and I like this bold orange colour.- From Amazon.
