I am also looking for recommendations from satisfied users for extreme cold weather mittens that will be suitable for commute cycling at -5°F to 20°F ambient temperature. Waterproofing is not a requirement since they will never be worn above freezing or used to handle snow. Windproof is essential to avoid wind chill. Price, within reason, is not an issue. Will wear with my own liners or preferably with a mitten liner that comes with the mitten.
