On a serious note, actually MAN is still trying to CATCH UP, not stepping back....
Man STILL can't out do mother nature on a fiber such as wool. No man made fiber is as durable either. I think you need to 'read up' a bit more. Lots of miss info out there. Lots of different wool types, wool constructions, wool fabrics, etc.....
And, even cleaning...which is rare if you dress properly underneath. .....and you can even buy WASHABLE merino thermals that you out in the machine.
Not really sure what the intent of this thread is, but a lot of positives have come out in the defense of wool from an original post that seems bent out to slam it.
I also like the Alaskan analogy....
Wonder what fiber you would want if you were stranded???
Wonder if you had to live in the woods for a couple of years...would you want a fleece blanket or wool blanket....which one do you think would last the longest and keep you the warmest?
