I'm with Chris on this one and picked up a Devold sweater 18 months ago in Bergan. Luckily it was half price and cost around £80
Looking at their web site really is a bit confusing. They appear to have a lot of designery models now in their 2006-07 range? I couldn't even find my model which is the traditional 'Icelander' or 'Islender'. But nosing around I eventually found it in the 'Protection' section
It is a lot more traditional and simpler than the others and a superb sweater with really soft but durable wool and good and thick (pre-washed and pre-shrunk). The link is here;
Devold - Icelander Sweater
Blurb:
The Devold Icelander is a robust and thick wool garment made according to traditional and timeless Norwegian pattern. The curling of the wool and the garment?s volume and thickness provide excellent insulation against cold. Wool can absorb a significant amount of condensation and still keep your body dry and warm. A Devold Icelander also provides a high degree of protection against rain and snow.
As sales speak goes that's pretty spoty on actually from my experience.
There is also an open/ zipped collar version called the 'North Sea' linked on the same page. I also picked up some merino wool hunting socks which are superb (can't see these though) and the merino wool underwear is really rated but pricey.
There are some more tradtional models and the ones mentioned on this web site which gives prices in euro and ship to UK. All prices are tax free and postage per item is about £14 for Air Mail. All in English and lots of info.
