Love a scarf, silk, sea island cotton, cordrouy...love em all. I like to wear a silk scarf under a mac or jacket, not much cop at keeping my neck warm but looks good IMO. Current fave a Paul Smith job from a couple of years ago.

I will wear one (typically a solid, like burgundy or navy) under a leather coat to protect the collar from skin oils when the weather does not call for a wool scarf. I would also consider a solid one-side/paisley or neats the other-side if I could find one.

If silk is enough for Canada, what would you wear in France?

Where would you wear cashmere then ?

Ernesto,

I call a normal condition anything short of a good old-fashioned snow storm.

In some ways the eastern part of Canada and America is even colder than Colorado as the climate is dry and cold in Colorado. I can't explain what i mean by dryer when it still snows but it is true.

For what it's worth, I think silk scarves are great.  I have a lovely Paul Stuart dble face silk / cashmere that I got this Xmas, and I really like it.  The one I'm lusting after the most right now is the Drakes of London dble face large / small dots printed on silk.  I think it looks very smart. 

There's a series of shops here in Paris called Arthur & Fox and they have a large, heavy silk square with white dots woven on navy that is superb, currently 130 Euros down from 180.  Still an expensive luxury.
