I love pogies or Moose Mitts, too. They let me wear my summer gloves year-round without having to add layers.

Both mount on your handlebars and block wind. Pogies add closures around your wrists to block ALL air, and are constructed like miniature sleeping bags for warmth. Moose Mitts are more just wind-blockers, with some fleece insulation. When I switched to Moose Mitts, I expected to have to put up with less comfort, but it never happened. Check them out.
