I tend to believe that the poly blend works as good for me as under-armor.
I agree partially. I have welcomed the advent of these new garments. I like less bulk, equal warmth which equates to greater mobility. The poly blends work very, very well. But, they will stink after first wearing & I don't like that. I will pay the money for the effective thinner stuff.
I do have a King of the Mountain wool coat. That thing will cook toast by itself.
