I like leather gloves lined with fake lambs wool, fitted loose. Mine probably came off the Wells-Lamont display at the hardware store. Easy on/off is a plus, especially when the old schnozz gets to running. That, and I can ball my fingers up in the palm area for a quick warm up.
The ones I have now are getting pretty grungy. Think I'll stop by the Surplus store tomorrow and see if they have any lined leather gloves.
I'm sold on leather. I use unlined in coolish weather, and only wear fingerless biking gloves in the heat of summer.
