Instead of hearing what you all wear to look your best on the mountain, I want to hear what you opt for as a base layer. Particularly for your bottoms. I used to use warm-ups (like for running) and they're full of holes and shit, so they need to go. I know there are under armour options, hot chillys, etc. I was hoping some of you might shed light on what works best for you.
Thanks for the input.
