As it goes, earlier this year I had to ski through -18F on Whiteface summit and found gloves are not really the right choice for such temperatures. Long story short, I ended up ordering Mountain Hardwear Medusa gloves from SierraTradingPost at a really nice discount.
Got them earlier today and was a bit disappointed. They just don't seem to be all that warm. While outer mitten seems to be very well made, inner lobster claw liner was clearly not designed for low temperatures. What are my choices when it comes to buying a good, really warm liner? I would prefer mitten style (since I will only use gloves during really cold temperatures and would prefer my fingers staying all together) liner, but would consider other choices if necessary.
