I (almost) loved the Haglofs couloir pants when my former employers used to supply them for me. Good weight and length, they went on in the morning (over powerstretch) and that was the bottom-half taken care of for the rest of the day, whatever the weather did, hot or cold.
Now I need to buy something similar, but one things stops me from getting another pair of the same; the bagginess of the lower-leg. I tolerated (and patched up) the inevitable crampon damage, but I suspect that there is better kit to be had.
Sizing and fit will be an issue - I did like the fact that Haglofs seem to design around a chunky "northern European" physique!
