Outdoor Research Prevail Heated GORE-TEX Mitts

Backcountry.com says:
Tested in and approved for the harshest conditions by Outdoor Research ambassadors, the Prevail Heated GORE-TEX Mitten dreams of deep alpine lines just as we do. The weatherproof build blocks out the wind and the wet, while the heat-trapping fill and fleecy lining hold in the cozy. At the touch of a button, we get a boost of warmth, choosing from 3 customizable settings, while the touchscreen compatible thumb and forefinger let us snap pics without subjecting our hands to the cold.
