Here's my experience with it, if you have a hairy body it will irritate the crap out of you.
It did me anyways. I have chest and stomach hair. I couldn’t stand to wear it and I was just trying to play golf in it.

Now the shorts don’t bother me at all and I wear them all summer long when I’m on the bike.

 

You would be surprised. Last winter we had 42 days when the temps never reached 32. There were a couple of mornings that it was 20 degrees when I got on the bike to ride my 60 miles to work.

I don't think the UA is worth the money to combat the cold. Heat...yes.

I've been buying silk long drawers and LS T-shirts as a base layer. Then fleece lined jeans (Bass Pro Shops) with chaps. On top, Columbia fleece mock turtleneck, heated vest and leather jacket. FF helmet with backlave. With the heated grips and heated seat on my FLHTK, I stayed comfortable all winter.
