I recently bought a set of the Under Armour cold gear just before the modern gun season. I bought it at Dick's and it is expensive, but in my opinion you get what you pay for. Somebody mentioned the walmart type. It is great for mild to cool weather, but it doesn't compare to the under armour in cold weather. I also bought the socks as well. The "UA" is 2 sided and that is what makes the difference between the others, and I would assume that is what runs up the cost. Hope this helps.
