No more wool for me now for years, Polar Fleece and the like do a better job. Washable, nothing eats it, does not shrink, smells less, if I go throw the ice I can ring it out and it still retains heat ( speak from experiences), less bulky, does not "catch" hooks as easy as wool, MUCH lighter and best of all I can get it cheaper! It's not that I don't like wool, I do and use to wear it all the time, but Polar Fleece works better in so many ways...
