Agreed that at some point (different for all) gloves are worthless and lobster glove or regular mittens are required. Look at pogies as a possibility and when it's crazy cold or as a safety item, bring along some Grabber chemical packs but know they take 10min or so to warm up well. I'm sure they have saved my hands and feet from severe frostbit on more than one occasion. Don't bother with the "toe" chem packs...not really big enough to help in cold temps to any meaningful degree.
