I have an old Norwegian army sweater which is fantastic. I looked for a source but couldn't find any. Pity, it is the best sweater. It is long, long sleeves with a thumb hole so you can pull the sleeves over your hands, collar can ride high. It covers all of the normal gaps, is exceptionally warm and durable. it carried me through the mountains of Afghanistan and still looks good. I traded a poncho liner for it in Bosnia, and now I wouldn't trade it for anything.

I have some Swiss army wool pants which are exceptional also.
