Two have posted about wool gloves/glove liners (Fox River @REI and Arc'teryx). I use a Smartwool version.

These work great, but if not careful one can wear a hole in the finger tips (for the smartwool and the arc'teryx there are some user complaints about this) Sometimes there may be a seam where the thumb is sewed onto the body of the glove (visible on the arc'teryx, smartwool doesn't have one) This can create a pressure point and lead to discomfort.

The Fox River version looks promising as it has some acrylic mixed in (making me think it is more durable than wool alone) and doesn't have the seam.
