My favorite gloves for riding when it is really cold, or wet -- are
ski gloves. Not the really thick kind of ski gloves, so my hands
still work, but they are warm and waterproof and breathable. I think
I got mine from Sierra Trading Post. I've also got some barn gloves
that are thinsulate insulated and are goretex, so even if my hands
get wet filling troughs, they stay warm and dry. Those I got from
Cabela's. Here are some links. Karen
