Tumble Dry Low with 2 clean tennis balls, Remove Promtly from Dryer
Ensure garment is thoroughly dry before removing it from dryer
Do not Iron
Do not Dry Clean


When your down garment has lost it’s loftiness it is recommended that this garment be washed.  Although necessary, it is best to do it as sparingly as possible.  Use a front load washing machine and a down specific detergent such as ReviveX Down Cleaner Concentrate.  Use warm water on permanent press or gentle cycle and rinse twice to ensure all cleaner has been removed.

Remove excess water with a towel by patting dry.  Dry the down garment on low heat with two clean tennis balls to help regain loft.  If you don’t have any you can substitute heavy socks rolled up.  It is very important that you dry your down garment entirely which may take upwards of 2 to 3 hours.  Your down garment will not regain its loft until it is fully dry.  Store unstuffed in a dry place.
