RestAssured™ Commitment to Quality In purchasing this down product from Frontgate, you can RestAssured™ it is 100% allergen free. Allergic reactions to down products stem from the dust particles, dander and oils that are embedded in unclean goose down. Thus, to ensure the highest hypoallergenic properties, our down goes through the rigorous RestAssured cleaning and drying process. This method cleanses down at twice the U.S. government standard. First, the down is sanitized and heat sterilized (washed, steam dried and cooled) at temperatures that exceed 120°C. Next, the down is thoroughly washed and dried again before being tested by International Down and Feather Testing Laboratory (IDFL) technicians for complete cleanliness. This stringent process ensures a high quality down product that is free of all allergens. RestAssured.
