Arc`teryx Powderface Goggle Case is constructed on ePTFE foam laminated to a nylon face fabric and brushed fleece. Arcteryx advances ever onward to provide their customers with the best products possible, by exploring new technology with materials that perform to their high standards and designs that are innovative, yet fashion savvy. Defining evolution in action, Arc`teryx is named for the Archaeopteryx Lithographica…the first reptile known to have developed feathers for flight. Kind of makes sense.
