The Feather Scientists

International Down and Feather Laboratory, or IDFL, is one of the world's foremost authorities on testing down and other filled textile insulation. The outdoor industry throws around terms like loft, fill power, down percentage, and DWR, but what do those terms tell us? This film reveals IDFL's procedures, showing what the numbers on the spec sheet really mean, and gives a never-before-seen look into KUIU's process for certifying the Toray Quixdown found in our Super Down products.
