How Often Should You Wash Your Sleeping Bag?

Unless your baby has poo-ed or pee-d in it, you really don't have to wash it that often. You can pretty much wait till it actually looks dirty before washing it.

Otherwise, you can continue using it as is.

We do recommend having at least 2 sleeping bags around.

The last thing you'd want is for your baby to have a leak in the middle of the night, and not have a fresh, new sleeping bag to put him/her into.

Washing Cotton Sleeping Bags

One of the main benefits of cotton is that it's a durable fabric.

As such, it can be machine washed with your other garments.

Having said that, because it is still a natural fibre, it is best to use only cold to warm water (up to 40oC) on a gentle spin cycle.

You'll want to avoid bleach or strong detergents. Also avoid using fabric softeners/conditioners.

For drying, line dry or tumble dry with low to no heat. 

Washing and drying on high heat can lead to shrinkage.

Washing Cashmere or Merino Sleeping Bags

Cashmere and merino are also fabrics used to make sleeping bags.

Like cotton, they're both natural fabrics which is great for sleeping.

They're both warm, soft on the skin and highly breathable.

See our article on the benefits of cashmere.

However, unlike cotton, cashmere and merino are types of wool and they are not particularly durable. It does require a little more effort in washing.

Hand Wash

It's recommended to hand wash your cashmere or merino sleeping bag.

To hand wash, gently massage your sleeping bag in cold to lukewarm water mixed with some baby shampoo or wool-specific detergent.

Do not use any bleach, fabric softeners/conditioners or any other strong detergents.

Thoroughly rinse off the detergent with clean water before drying.

Machine Wash

Machine wash is generally not recommended.

However, we know that being a new parent is exhausting and any shortcuts are highly welcomed. If you decide to machine wash your cashmere or merino sleeping bag, make sure to put it in a mesh bag on a delicate cycle.

Use only cold to warm/lukewarm water, up to 30oC.

Dry Clean

You can also dry clean your cashmere or merino sleeping bag.

However, make sure to use a reputable dry cleaner.

Some of them use harsh chemicals in the dry-cleaning process which will ultimately damage your sleeping bag.


Squeeze gently to remove excess water.

You can also roll in a towel to dry it further.

Do not wring or stretch it excessively.

Lay flat to dry away from direct sunlight.

Following these washing instructions will help to prolong the lifespan of your sleeping bag. It's also a good idea to always read the care label that comes attached to your sleeping bag. Once you get the hang of it, it'll just become second nature to you.
