Wash and Care Instructions
Per Therm-a-Rest

WASH: Spot-clean as needed with a damp sponge. Machine-wash only when necessary in a largecapacity, front-loading washing machine, using 3 oz. of Nikwax® Down Wash Direct™. Close all zippers and fasten all snaps. Select cold water and a delicate cycle with two rinses and an additional spin cycle. If you do not have Nikwax® Down Wash Direct™, a mild detergent can be used but will not restore your down's hydrophobic properties.

MACHINE DRY: Tumble dry in a large dryer on low heat. Check often for overheating and manipulate the down to reduce clumping. Adding tennis balls will help to reduce clumping.

HANG DRY: Use a well-ventilated, low-humidity environment. Hang and undo all zippers and snaps. Manipulate the down often to reduce clumping. Hang drying down can take 48 hours or more.
