When I lived in NH, and about froze my nethers off, I got some from the Campmor catalogue. Now I'm on the Winter Silks mailing list, and they have quite a selection. I recently scored some silk/cotton sweat shirts off them. I had three that I found NWT in a thrift store a few years ago, and I have worn them into rags. The combination of cotton and silk in a sweatshirt fleece is perfect for my "lifestyle" - not too hot, not too cold, just right. And they look classier than Hanes. ;-)
