How to wash a down sleeping bag?

Washing a product that contains feathers is much simpler than it appears, so long as you take a little care: down doesn't go well with water and clumps when it is damp.
Avoid washing your sleeping bag too often if you can and use a sleeping bag liner.

You will have to fluff up the feathers and down at all stages in the washing process:
- Zip up all the zips on the sleeping bag and place it in the washing machine
- Add wash balls or 2 or 3 tennis balls (ideally worn ones to avoid loss of yellow fibres).
- Start a wash cycle at 30°C using your usual washing product (smaller dose than usual) or a washing product for duvets, that preserves their insulating qualities
-Rinse twice and set on very delicate spin to avoid feathers clumping together

How to dry a sleeping bag?

Generally speaking, using a tumble dryer is much more efficient and less tedious than line drying. it is time to check out the local laundrette or ask someone to borrow their dryer!
- Tumble dryer
Place the sleeping bag in the tumble dryer, with the tennis balls or washing balls. Start 2 to 3 delicate drying cycles and beat/shake the duvet between each cycle to break up clumps of feathers and down.
- If you cannot get to a tumble dryer?
Dry the sleeping bag flat on a clothes rack and beat/shake it regularly to prevent feather clumping.
Ideally, dry it in a warm place at room temperature (not on a radiator... I see you! ). If there are still feather clumps, it hasn't dried properly.


Almost all sleeping bags are water repellant but not waterproof as waterproofing would prevent good evacuation of the body's moisture: it is therefore impossible (and useless) to waterproof them.
To make them waterproof, it is best to use a sleeping bag cover.

However, water repellency can be re-activated, meaning its ability to repel water and not absorb water droplets on the surface.

The different steps to restore the water-repellency of a sleeping bag:
- Washing: follow the instructions below.
- Wash-in product: use a water-repellency reactivation liquid in a tub of water (30°C and 15 minutes of soaking) or in a machine with tennis balls (in the softener compartments, delicate cycle at 30°C).
- Activating it: it is activated either by heat or tumble dryer (follow the instructions below), or on a clothes rack, using a hair dryer on gently heat.

How to store a sleeping bag in its cover?

Good news, most sleeping bags are now designed to be tidied away easily: no need to fold them carefully to get them into the cover (even for the ultra-compact ones)!
It is particularly true for feather duvets: you must always stuff the sleeping bag into its carry or compression cover, because if you always fold it the same way, the feathers will crease and flatten. A flat feather is less insulating than a feather with intact structure.

Before storing your sleeping bag, check that it is dry to avoid moisture. Then place it in the cover, starting with the feet, to remove air, up to the hood.
