What is an All-in-two Nappy?

It’s another day on Google trying to wrap your head around the cloth nappy world. More and more jargon is being used the deeper you get and your head is spinning. What TF is an All-in-two nappy?

As always every brand, manufacturer, maker and pattern differs slightly and each or these attributes are not exclusive to each other. They can appear in ANY combination in ANY size option.

So what’s an All-In-Two Nappy? Why use it? What makes it different from other nappies?


The All-in-two nappy is up there in popularity amongst the Modern Cloth Nappy (MCN) styles. I can be made a couple of different ways but conventionally it works the same. They are made in two parts (the nappy shell and insert) and joined together with snaps.


The nappy shell has a couple of possible combinations of construction. They are as follows:

  • PUL (Polyethene Laminate) fabric as the waterproof outer and an absorbent/moisture wicking fabric such as microfleece/suede cloth/terry as the inner fabric. Sewn together on all sides or with a pocket option.
  • PUL fabric as the waterproof outer and another layer of PUL fabric as the inner fabric. This makes a shell that you can reuse by swapping the insert. These can be called a cover as well.
  • PUL fabric as the waterproof outer with no inner fabric. Patterns differ with this style in how they attach the elastics. This option is also considered a reusable cover.
  • Fitted Nappies can also be All-In-Two*

The fabric is cut and sewn together in a shape similar to a disposable nappy. Like all aspects of the nappy, there are varying types of elastic configurations. All the All-in-two nappies I have come across have at least leg elastics and an elastic across the back.

All-In-Two nappies come with their own inserts (although many are compatible across brands). They will have a female snap in the nappy shell and a male snap on the insert. The nappy may come with multiple inserts that either snap together or after the initial insert attaches to the nappy, lay on top. The inserts can be made with a range of fabrics and may or may not be topped with a “stay dry” fabric such as microfleece. The insert fabrics can include:

  • Microfibre covered in another fabric such a microfleece (microfiber will cause rashes and irritation if placed against baby’s skin)
  • Bamboo
  • Cotton
  • Hemp

Each of these fabrics have their own advantages and disadvantages and it depends on the individual child as to the best combination of fabrics.

At what size will they fit?

The All-In-Two style does not dictate the sizing or closure of the nappy. They are most commonly available in OSFM (One Size Fits Most) but can be found in newborn and sized options. These nappies can also be a snap or Velcro closure.


How do you wash and dry them?


I will be writing an article about my personal wash routine in the future, but highly recommend heading over to Clean Cloth Nappies who are the experts in this area with extensive knowledge and experience in all areas and situations. 

Generally speaking, you can’t adequately wash cloth nappies (your dirtiest laundry) in cold water with minimal detergent. You need a good, well rounded, hot water wash routine to ensure your nappies stay in tip top shape and continue to be healthy for your baby. 

A good quality PUL can withstand the temperatures (up to 60 degrees) called for in the Clean Cloth Nappy washing routines. PUL is not however recommended to go through the dryer or be left in the Australian sun for prolonged periods of time. Personally I dry my nappy shells inside on a clothes horse to extend their life. Inserts can go through the dryer with no problems.


In Conclusion!

This is a great option for everyone in their cloth nappy journey. They are less time consuming to prepare than pockets but more efficient in drying time than All-In-Ones. 

Whether you are a sleep deprived first time parent learning how to hold a newborn let along change one or you are a seasoned mumma with a crocodile rolling toddler, these will make the changing process so much easier.
