Who Invented The Down Jacket?
Down jackets are really a very simple idea: Take the lightest, most waterproof, most cushioned, most protective (too many mosts?) insulation materials in the natural world, and use it to make functional clothes.
The idea is so simple, and so useful, that the American Army changed their rules to allow the inventor to put his company’s logo on their clothing. But imagine coming up with that idea for the first time? And imagine who invented it?
