I was pretty disappointed with these leggings.  It's pretty tough to explain.  It's like the cold goes up inside your outer pant leg, then hits the under armour, head on, causing the skin to feel the cold!  You feel me?  LOL!  I won't be buying any more UA products designed for the cold.  Maybe the 2.0 or stronger would be a better choice, but I'm not risking it.  This stuff is EXPENSIVE, for me anyway!  I'm sticking with the cheap waffle pattern thermal underwear.  Works just as well, if not better than the UA stuff, and is 1/10 of the price.  I do a lot of work outside and I need reliable, warm under clothing.  These Evo Coldgear Leggings do not cut the mustard.  I wouldn't recommend buying them, if you're working in the cold, like Canada, where I am.
