Another slant: if you think you may spend lots of time in the future hanging round in cold places, a pair of primaloft type trousers can be rather nice - and good survival gear too, should ou be stuck out somewhere. Most have full zips so you can pull them on even when wearing crampons. Fairly weather resistant, too. Arguably a luxury, but damned nice when conditions dictate! I suffer from cold feet - that's how I justified my second pair... I lent the older pair to a mate on our trip north last winter - but as it turned out to be one of the mildest, they weren't used. But great for hanging around in. Another mate and I took same to Patagonia last Nov/Dec, which enabled us to sit around camp in the mornings and evenings to enjoy being there to the full.
