I can tell you that not all wool is " created equal" .

As has been pointed out wool is a wonderful product, time tested, and proven over and over. I have wool pants from Filson that are forest green that I use with a camo cover. I also have Cabelas camo wool pants that are a blend. Both good products.

I have some bibs, coat, and shirt that are made by Columbia. They are only 65 % wool and are certainly warm but not of the same quality as Filson or the Cabelas blend. Of course they are cheaper too.

Not everybody can afford $300.00 for a pair of pants or $400.00+ for a jacket from Sleeping Indian or King of the Mountain.
