In my personal experience after about -10F it doesn't feel any "colder." It just hurts more when you have any exposed skin. (Which you shouldn't have at those temps anyway.)
Also, important to note, humidity plays a huge part in how cold these temps feel. Humid places like much of the east coast feel much colder than dry places like here in Bozeman.
