Well when I purchased my Zemke Replica RF1000 a few months ago I was very pleased with it. However now I'm not very happy with it at all. You see here in AZ it gets a bit "warm" to say the least. When I got the helmet it was still "cool" out and hadn't reached the usual summer heat yet. The past few weeks it has been over 100 degrees almost every day. On Saturday I attempted to wear said helmet for a ride to a friends house and about died. This thing is NOT designed for hot weather climates in my opinion. I Really like how my Arai Corsair vents, almost too good sometimes, but since it is a one of a kind paint scheme I hate to wear it. I guess it's time to get another helmet. I already have 5, so what's another, right. Just call me the Chain of helmets.
