the best hands down is SG (Stone Glacier) puffy pants OR Kifaru Packlock Arctic pants!!!
I was surprised as well. I think often the worst part about sitting in the cold is my butt and knees leak all my warmth because that's where my pants are tight across my body. With the waterproof/windproof panels of the timberlines and the kneepads, I think it protected me from the wind more than I realized.I've looked at those UA puffy pants and they are pretty nice, but I'm more amazed that you sat in 15 degree windchill in merino base layers and timberline pants and didnt get cold for 3 hours!
