This is nice wool and it's VERY warm although it's very thin!  My only problem with it is that it's HUGE.  I think they should make more than one size.  I bought this for my husband who works outdoors and after very little it's all stretched out and he has to keep readjusting it (causing more stretching).  I tried washing it in hot/cold and now it has pilling all over it.  I think I'll try to sew it to make it smaller just so he can get some use out of it.
