Ideally you would want something that is lightweight and corrosion resistant. I suppose titanium wool would be best, but I don't know if it exists. Stainless steel wool would be better than regular steel wool because it would last longer. Some of the best suppressors don't use steel wool, but use baffles instead. Some companies use copper wool, but I suspect that it is not as good as stainless steel. You could try using aluminum turnings from a lathe, but I don't know how long they would last.
Long wool coats can be bought from many different stores and retailers. Some examples of stores that sell long wool coats include L.L. Bean, J. Crew, and Lands' End.
Alpaca wool is fine, soft, and generally comes in 8-12 inch long fibers. It has a good luster and is an extremely good insulative wool.
