Wow, keep the tips coming. When I visited Crankin in Boston, I wore a goretex pant over my jeans, and was OK but felt really dorky. I then proceeded to buy a primaloft coat and tall boots which worked fine in Boston over jeans and ibex on top, but I think it was only in the 30s.
But, now I am looking for travel clothes to take me from southern portugal to switzerland with the smallest number of pieces that can be combined in lots of different ways. And I think Switzerland will be colder than Boston was, and I will want to ski. I guess this is getting mixed up cuz its not always clear which responses are good for just walking around vs skiing, and I guess I am looking for clothes that in different combinations will work for both. So, its sounding like if I want to add one more piece the alpstar pant will do it, I just need some sizing help on it from anyone that owns it (do your actual body measurements match the size you ordered?).
But Catriona gave me another idea. The shebeest windpro tight is lined with powerfleece. I have one pair of wool pants that are a size too big, so if its really cold in switzerland I could put the tight on under the pants, and if its less cold pair them with the woolies for walking around.
