Winter and I, we don't mix. My fingers get so cold, even in -2 degree weather that they become pretty much useless if exposed to the elements. I wear the black wool ones first then followed by a pair of neoprene Rossingol cross country skiing gloves. I found the x-country skiing gloves are designed to be tight around your hand/fingers and you have pretty good dexterity. Also they don't have much "rubber grip" so they don't interfere while I use my center pin.
Needless to say, I still find myself taking them off and putting my hands into my sweater to warm up or building a fire to warm them up again. I am the extreme case though, some guys use the little black ones all day while I freeze with my double layer :lol:
