Scott,

I certainly wouldn't be the one to say you are missing out on anything because you don't own a wool outfit. A lot of people prefer synthetic especially when comparing cost. What one person really likes another person may abhor.

Wool is expensive but taken care of properly it should last a lifetime.
As far as the restriction of movement issue goes, the wool by itself is not restrictive at all. When I look at my unlined wool garments I am always amazed they hold as much heat as they do because they really are not that thick. That is the beauty of wool, heat without bulk. Insulating it can bulk it up but not worse than insulated synthetics.

There are many that say a bitter wind will go through wool like poop through a goose so it would not be a bad idea to have some windstopper on the inside of one's personal wool and even some insulated wool products on hand. Personally when those kind of winds are blowing I haven't found much it won't go through.

Wool can absorb 30% of its weight in moisture and not feel damp. Itstill helps to retain a certain amount of body heat under those conditions, something that very few if any synthetics can achieve. However it can get heavy when totally saturated so if you are hiking in the high country this is something to consider.

If I was to sit in a treestand from dawn to dusk and could only pick one garment to use for comfort in cold weather(excluding that giant body mitten used in extreme temps), it would be a pair of King of the Mountain/Sleeping Indian bibs. Of course most of us are not going to spend $400.00+ on a pair of bibs. Jeff's lined bibs in woolrange from $350-390.

On the down side, some we have already mentioned, obviously price, heavy when saturated, it does pick up burrs, some wools recommend drycleaning only (I wash all of mine by hand. It never sees a dryer and I have never had a problem. Finally when the temps reach greater than 50 degrees some layers are coming off...
