Greetings to all!
I belive JIMs basic question is why are our New York style helmets shaped the way they are. The short answer JIM, is that it keeps the water from running down the necks of our turnout coats. You can even purchase some in leather. (these are much more expensive and heavier to wear, but some guys like to spend money) The fire service is rather tradition heavy here in the US and therefor somewhat slow to change. I have been a firefighter for the last 17 years and have recently had a chance to try the helmets that you were displaying under actual structure fire conditions. It is definately lighter to wear, and offers more complete side protection. But that being said I would have a very hard time giving up my New Yorker.
Thought it was time to come out of the woodwork so to speak,I have been lurking about for the last four years or so and have learned much from many of you. Thanks!
