I know that the Cockpit G-1 is sold in the Navy Exchange (NEX) stores. Maybe that is what they mean by "supplied to the U.S. Navy." I have never seen an issued G-1 from Cockpit.
I actually thought the same thing.
I don't want to get too down on the Cockpit or any other company. I understand that these guys are in business to sell jackets and you sell the dream as much as the product.
But having been the guy that walks around in his Banana Republic, removable collar, lamb skin, G-1 thinking I was sporting the real deal, I can appreciate that feeling that you get when you find out just how wrong you are.
