How do we cope with the cold? I use the Bag Lady technique; lots and lots of layers. My body stays pretty comfortable, but my hands and feet get cold. I pre-heat my gloves and socks by the fireplace, and I keep my boots on a boot warmer/dryer.
The horses' winter coats range from extremely dense to barely there. Zan is a wooly bear. He is comfortable in a medium/heavy blanket at -13 degrees. Reggie and Boomer have average coats. In extreme cold, we double-blanket them with a blanket covered by a medium sheet. Delicate Paj has almost no coat. He wears a wool blanket liner, a blanket, and a breathable Gore-Tex sheet. Geez.

We are very careful about how long we let them out on these cold days, trying to balance the need to move against the danger of getting too cold.
