These guys wearing just Kinco gloves when it's 0F : skiing
I have been wearing Kincos for 10+ years and won't go back to standard "ski gloves" for anything! Get yourself some Atsko Sno-Seal Beeswax Waterproofing. Heat the gloves up a bit in the oven (150 degrees). Apply wax. Bake for a bit. Repeat a few times until you have a good coating.
