In the opinion of the chairman, the "Ears" have it.
I can only find the Pro Ears (Ridge Line) muffs in the Natchez catalog, but they don't have the Pro-Slim model. They have the Pro-Mag LE which they say has even more insulation that the Pro-Slim. Does anyone know of any other retailer that carries them? I'd like to compare prices. (I've checked Midway and Graf.)
