Oh Catriona, you have me so overwhelmed. I just looked at that arcteyrx tau pant and it looks lovely for walking around.

Maybe I should order both the alpster and tau pants in assorted sizes, and return what doesn't work.....

I do have a number of ibex tank tops that I use for around here under blouses, so I am good with those. But that's another great idea, layering those under one of my base layers.

So, while I know everyone is diff, Catriona tell me another thing, what would be the warmest temperature you would wear the tau and alpster out in (not for sports now, just walking around). I know that I froze in DC in lined wool dress pants in the 30s with wind (I think it was the wind went right through them), but I had no base layer on either.
