The helmet in the OP's post is cool looking but I don't know if it's what I'd choose for commuting. As Adam said, my regular helmet with a balcava and my hoodie (its a runner's pullover that has a hood just large enough to pull up over my helmet to block most of the vents) does just fine to about -10 degrees F. If I was going to ride much colder, I'd get a regular ski helmet and goggles.

Skiing and cycling involve similar speeds and hazards. Ski helmets are similar in design to cycling helmets with fewer, smaller vents and insulation (some have ear flaps). An added advantage is that they have clips to help keep goggles in place. This time of year you can find them at big discounts.
