Thanks Schwert, as I'm always looking for cold weather dressing improvement, I decided to investigate more about these famous Ullfrotte underwear. I found the woolpower products available in Canada from www.gransfors.ca I downloaded and will read their primer on dressing for the cold at http://www.woolpower.se/en/asp/kladigratt_1.asp

But the idea of mail ordering long johns makes me hesitant because these items should be form fitting without any gap and non restricting at the same time and be long enough also.
