Since we're not you, it's hard to tell you definitely what you need to bring and not. You'll probably be fine in jeans with woolies - have a heavier layer with you in case you aren't.

You can use the alpstars for walking around in - they're casual enough looking. You could also use them for skiing.

I've got a couple pairs of the prana fleece lined pants, that I absolutely love and they're kind of my cold weather walking around in pants. It's more of a flannel lining than fleece

Bottom layers - truthfully, while I have wool bottom layers, they really just don't tend to be as warm as just putting on some polartec powerstrech and I really don't use them as much. I don't like layering multiple bottom layers for skiing. It constricts movement a bit too much.

The arc'teryx rho ar bottoms are extremely warm. The cloudveil run don't walk bottoms as well:

I've got a pair of run don't walk boxers, that layers with some power stretch tights with an outer goretex layer and I'm usually good for down hill skiing.


I wouldn't use woolies on their own under goretex, because I wouldn't find that warm enough. I do have one pair of ibex tights that are fairly thick - they're the weight of the loose tights & unzip at the bottom, I think they're the energy tights:

That's my warmest wool bottom.

Polartec powerstretch dries quickly if washed in a sink or whatever.
