I just posted this in another forum, but I'll elaborate here.

Moose Mitts on the handlebars, gloves on your hands.

I really think trying to accomplish windstopping, rainstopping, finger warming, and unobstructed brake/shifter control with just a pair of gloves is the wrong approach. Moose Mitts stop the rain and wind, as well as doing a big chunk of finger-warming duty. Gloves finish up the rest.

It was right around freezing on my 13-mile commute home tonight. I wore my crocheted summer half-gloves under the Moose Mitts. I haven't decided yet whether I'm wearing them again tomorrow or switching to my thin summer full-finger gloves.
