Yes, I got a pair last winter and they are much warmer than normal ones. They also don't get soaked in the rain, although haven't been caught out in heavy rain yet.
I'm trying to resist temptation to get another pair this year.
Brilliant, I have a pair on my xmas list but was a bit concerned about the cost of them in case they aren't as good as they say. I have some musto snug jods but don't really like the design or the material so I have gone for the pikeur ones this time.
