I bought mine for sitting around the fire http://youtu.be/Ni7a6BVhYZM
Rothco 90% - $35 - http://www.thepathfinderstore.com/90-wool-blanket/
I haven't been able to find new, retail 100% wool for a decent price(have to go to army surplus stores or antique/thrift shops). That site also has 100% but it is $175 IIRC.
I got my Polish a year or two ago and it is really nice . Smelled pretty chemically when I got it . I washed it in Ivory on gentle cool cycle and hang dried it , and it's fine . I bought it for about 30 with free shipping . There out of them now ofcourse .
