Might look here for boots.

I've been trying out Kenyon base layers for a year. Rayon (bamboo)/nylon mix. So far I like them. Soft, warm and don't seem to retain smell.

Polypro liner socks wool outers.

Beany for the head. I like fleece. Usually carry a couple.

Carharts for coats and Dickies for pants.

Patigonia has a couple of big sales a year. You can't beat there base layers. Dickies has an online sale close to Xmas, IIRC.
