Before Merino, Cabela's used to sell silk long underwear as a base layer to the old scratchy wool. I bought a heavy silk top to go under a Stanfield top...Stanfield, talk about heavy duty and scratchy!
Wool over silk is a great combination for comfort and warmth. I have some the old Cabela's heavy weight silk. It is really good stuff. Unfortunately, nobody seems to sell the heavy weight silk anymore.
