Sheep fleece is usually shorn from the animals annually. Fleece from other animals may be harvested on different schedules, depending on the animals and the climate in which they live.

Merinos are sheep that have long, silky wool and are bred for their wool production.
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.
The kind of goat that creates long, silky wool is the Angora goat.
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.

I prefer wool. I think linen wrinkles too easy and looks sloppy after a bit. Wool holds up well, stays neat, and can be worn much of the year. A good wool suit will last years.
Yes wool is strong, this is because sheep drinks water and eat grass. That is the only reason why wool fabric is strong.
