my results are skewed 'cause I have Reynaud's too but here are my results - both scored high dexterity
- cold (haven't ridden yet below 20), Seirus glove liners, Burton snowmobile mittens
- light cold, same liners, Champion C9 convertible glove/mitten (Target)
for colder than 20 I'm going to put glove warmers in the Burtons (they have a cool little pocket)
