GERMAN SINGLE PIECE COLD WEATHER FLIGHT SUIT

I do not know what the nomenclature is for this extreme weather high altitude leather one piece flying suit. I have seen similar cold weather uniforms but they differ with two zippers instead of one running from the throat to the crotch. I would presume that they are a later design as I don’t think this style would be noted for quick escape from it. The coverall has multiple zippers and all work except the right leg bottom zipper. The mfg tag in inside the right side inner wall. This thing weighs a ton shipping will be expensive. The last time I had a chance to buy a similar set the guy used it for ice fishing and ruined the bottom of each leg. He said it was the only thing that kept him warm and he didn’t need a wind breaker. Condition very good ++++
