International Down and Feather Laboratory, or IDFL, is one of the world's foremost authorities on testing down and other filled textile insulation.

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.
