MM88,

I have no experience with wool outergarments as I was always under the impression that they were not water repellant or wind proof. However, I am sure they are probably some of the warmest garments out there.

Myself? I hunt almost exclusively with a variety of Cabelas outfits right now. I like their Revolution Fleece both insulated and uninsulated for either late or early season respectively. It is warm, waterproof, windproof and carries Cabelas typical return policy. It is also relatively lightweight and very durable.

Price varies depending on your size and whether or not it is insulated.
