Open cockpit headset microphones

[jetsareforkids]

So I've been doing some reading on mike muffs for open cockpit biplanes. I'm currently using David Clarks in my new plane, and the foam mike muffs clearly are not going to work. I've seen people recommend leather mike muffs, where do you buy them and what works best for David Clark headsets? I have one with noise cancelling and one without, not sure if that makes a difference on the microphone
