How to Care for your Down Sleeping Bag or Quilt

Down sleeping bags and quilts do not need to be washed very often. Wash once after a long season or only as needed.

We recommend hand washing your down sleeping bag or quilt. 

How to Hand-wash your Down Sleeping Bag or Quilt 

  1. Fill your bathtub with warm water and half a cap of Grangers Downwash
  2. Keep the sleeping bag in the dry bag and remove it while it is underwater so that it doesn't fill up with air. 
  3. Swish the sleeping bag around for a few minutes. 
  4. Drain the tub, leaving the sleeping bag in the tub. 
  5. Rinse the sleeping bag with fresh water. 
  6. Squish the sleeping bag back into the dry bag and squeeze as much water out as possible. 
  7. For best results, lay the sleeping bag out in the sun to dry. If the sleeping bag has a darker shell material (for example black on the inside) face the black side up to absorb more heat from the sun. You will have to periodically pull apart any wet down clumps. It may take all day to completely dry a sleeping bag

Be careful of machine washing down sleeping bags. The twisting motion of a washing machine could potentially tear the shell or the internal baffles. If you do try a washing machine do so at your own risk using the delicate setting.

Some people use a clothes dryer with tennis balls to help break the down clumps apart, but do so at your own risk. High heat can melt delicate shell materials. Even with a dryer, it can take a very long time to dry a sleeping bag. We recommend drying your down gear items in the sun, or line drying indoors if outside weather doesn't permit sun drying.


Store loose (hanging in a closet for example) when not in use. Each bag has a hang loop at the foot. Alternatively, it can be stored loose in a laundry bag.
