IMO I would get rid of everything if i had to and keep the woolpower stuff. It seems $$$ at first but when you are out there and its really cold and blowing like its gonna be next week. You forget about the cost right away. If you compare it to the scentblocker underwear and the under armour cold gear it is basically in the same price range and it puts that crap to shame. Under armour cold gear is the biggest hoax going next to carbon hunting clothes.Another nod for good wool
