I picked up a Bern Macon over the weekend. I was quite dubious at first, but am actually very pleased with it. It is a bit warmer than my Bell Muni, but not overly so. The front vents get some pretty good air moving through. The Bern is also much more comfortable than the Muni, and far better looking IMHO. I have an smaller than average hat size for a man, and normal cycling helmets tend to look even more stupid on me than other people. The low profile skate style helmet looks a million times better.
