I can say that this is the best piece of kit I have ever put on my head. Brother, you hit it out of the park on this!  I also found a neat way of getting the wire out of the way. Ran the wire outboard of the chin strap/nape pad and tucked them in under the cover.  You will definitely be getting another order from me as now I will be needing a back-up set. “2 is one” and all that other good stuff.  I will surely be passing on the excellent find.
