Long haired wool works fine — at least at 1st. it is not moth proof and will sag. If you are going to use it i would suggest a 50/50 mix with polyfill to make it stay in place.
Mundorf angel hair is better, moth proof and without mixing it with polyfill it will stay in place.
Ps: No, I've no financial interest in Mundorf. Just sharing my experience..
Angel hair looks nice and gets good reports… i have a sample somewhere, but it is hard to get ahold of in Canada.

I’ve always favored Acousta-Stuf. It’s been my go-to choice for a long time. Affordable, no itching or nasty stuff getting on your skin or in your lungs. It doesn’t sag and there’s no worries about moths or mold.

'$360 USD for a kg! Very pricey stuff.'
Yes, but you don't need much.

Twaron Angel hair works excellent at mid frequencies. A little goes a long way (can clearly be seen in impedance plots). I found fiberglass (the itchy stuff) hard to beat at lower frequencies (in a sealed enclosure, wouldn't want it in a ported solution).
A combination actually worked remarkably well over a large range. So did wool felt on walls with fiberglass fill.

Here's a plot, but not with a pure fill of angel hair. I wanted a solution for the entire range I was going to use these drivers in (about 20 to 20 kHz ) so that's where my focus was.
I might have some more data saved somewhere, pretty sure I also tried Angel hair by itself.

Edit: I looked trough the files I saved, sadly no Angel hair solo measurements. I took those measurements on an older laptop and only transferred the plots that satisfied my curiosity at the time. I had about 3 days of testing all kinds of materials and combinations.
I finally opted for a combination of wool felt (real sheep wool) on all walls and fiberglass as fill. Nasty itchy stuff, but a one time deal putting it in a sealed enclosure.

Thanks a lot. Seems angel hair lowers the impedance peak around 180 hz a lot.
