How to wash a synthetic sleeping bag
Kathmandu's sleeping bags are durable and easy to care for. You can reduce the need to wash your sleeping bag by using a sleeping bag liner, spot cleaning marks on the outside with a damp cloth, and by using a sleeping mat.
You can machine wash or hand wash your Kathmandu synthetic sleeping bag. We do not recommend bleaching, ironing or dry-cleaning your sleeping bag. The fumes produced from dry-cleaning fluids can be dangerous and can age the sleeping bag prematurely.
Machine Washing Your Sleeping Bag
During washing, ensure all zippers and the velcro tab are secured.
Use a heavy-duty front loader on a gentle cycle.
Set to a warm machine wash (up to 30°C). Add a pure, mild soap, detergent or Granger's Performance Wash.
Handwashing Your Sleeping Bag
Fill your bath to a depth of 150 mm of warm water and add a pure, mild soap, detergent or Granger's Performance Wash.
Place your bag into the tub and gently massage the water into the bag by adding pressure from above with your open hands until the bag is saturated. When your bag is laden with water, do not attempt to lift it out.
Leave to soak for 1-4 hours, depending on how dirty your bag is.
Drain the water and then add fresh water, and massage the water into the bag again. Repeat this process until no suds are visible in the water.
Press the water out of the bag and express as much water as possible.
Fold the ends of the semi-dry bag in towards its centre and press firmly until water is expelled.
Drying Your Sleeping Bag
Once all the excess water has been released, you can tumble-dry your sleeping bag on a low temperature setting. Please note that excess heat can melt the fabric.
To air-dry your sleeping bag, lay it out flat on towels over two portable clothes racks.
Dry in a shaded area out of direct sunlight, as excessive exposure to UV will degrade the nylon shell fabric. A hot dry windy day provides the perfect conditions for air-drying your sleeping bag.
