Most of the time in the winter I use typical skiing/boarding gloves. There's lots to choose from. Probably more bulky than you're looking for but in my experience warm fingers in bulky gloves work better than numb fingers in non-bulky gloves.

When it's really cold I wear my ice fishing mitts. Very bulky but I can use them even with brifters. My biggest problem with them is that they're often too warm.
