    What is RDS certified down? It is an international standard designed to ensure the humane treatment of ducks and geese in the feather industry. For more information: https://textileexchange.org/responsible-down-standard/
    Which size sleeping bag should I order? XL sleeping bags are designed for users up to 6'6" tall. Regular size AMPEX sleeping bags are designed for users up to 6'0" tall. In general, you want to minimize the extra space in your sleeping bag to maximize heat retention. Therefore, we suggest choosing the smallest sleeping bag that fits you comfortably.
    Why are there two storage bags included? The compression bag is meant to be used in the field to minimize the size of your sleeping bag. The mesh storage bag should be used when your bag is not in use to minimize the chance of compressing the loft of the insulation.
