Great hat.  It looks great on my brother (for whom I brought it), and he reports that it is very warm in our bitter winter.

I have a similar hat, but I find the leather on this one more attractive.  Even if you think it looks a little silly with the ears down, it is the warmest design I've found.  Difficult to hear through, but certainly warm.  I favor real fur over fake fur on both practical and sensory grounds.  It is very soft and very warm even in bitter wind and cold and it lasts a lifetime.  Not everyone is comfortable wearing fur for ethical reasons, but for straight-up functionality, you can't beat evolution for building the best insulation.
