I haven't tried the garmets you are referring to. However, I do own some Under Armour and in my opinion...Under Armour=over priced.
The only article of UA I bought myself is a hoodie that I wanted to try about 6 years ago. I think It cost me like 75 bucks or something. It isn't a bit warmer than a cheap Jerzees. And it's got kind of a shine to it.
I also have a set (jacket and pants) of UA capture scent that I received as a gift. It isn't comfortable but it is fairly warm. I don't know that I believe in any of the scent blocker type clothing in doing anything other than separating a hunter from their money.
I also have a few t-shirts (also gifts). ALL of their clothing I have is super staticy...it just clings to me and does not feel comfortable at all.
In my opinion, I'm sure you could find something as good or better for a lot less money. I'll not drop any more of my hard earned money on something with a UA logo again unless they come up with something extremely impressive.
Once again, just my opinions on them....I'm sure others feel differently.
