Please note that the Ultimate nappy in the Art-Strolo-Sea release comes without an extra nap (3-layer bamboo insert) and has a smaller non-elasticised 5-layer hemp insert that will affect how the inserts snap together. However, we have done an absorbency test and the smaller size has not affected the absorbency of the insert. 

Please refer to photos to see the size difference of the inserts - all of them have gone through ~8 washes. 

The Ultimate nappies are Monarch’s signature snap and wipe nappy that can be used for both a day and a night nappy for heavy wetters simply by tweaking the combination of inserts. It’s a one-size-fits-most nappy that can last your child from infancy all the way to toddlerhood, making it a great investment, both financially and environmentally.

Why we love it

1. Customisable absorbency

The Ultimate Nappy  (Art-Strolo-Sea release) comes with 3 inserts that can be used in a variety of combinations to fit the needs of your child. This is the perfect nappy if your child is a heavy wetter, or for babies who sleep through the night (lucky you)!

  • 1 x 5-layer hemp insert
  • 1 x 5-layer bamboo insert
  • 1 x 3-layer bamboo ("Nap") insert

For some recommended insert combinations by Monarch, please refer here.

2. Wipeable shell

The Ultimate Nappy has a wipeable shell that is made of a waterproof material called PUL. This shell can be reused with a clean insert after a wipe down*, so you get more bang for your buck. It can double up as a swim nappy or a nappy cover too! Perfect for the kiasu Singaporean parent.

3. Leak-proof and maximum comfort 

Double-gussets — The outer gusset provides an extra barrier of protection against leaks. The inner gussets should be tucked into the groin area to prevent red marks on bub’s thighs.

PUL tummy and back flaps — The inserts are designed to snap into the shell under the front and back waterproof flaps, to keep the moisture from sitting against bub's skin (stomach and back) for extended periods of time. 

Thick back elastic This is to ensure the nappy sits as trim and as flush as possible against bub's back, to minimise leaks and any discomfort from a thin elastic digging into the back.

Larger Fit & Longer Wings The wing length has been increased to give you even longer wear out of your Ultimate nappies.


*If pee/poo has been absorbed into the leg elastics, or if the nappy was used as a night nappy, we recommend washing the entire shell instead of wiping it down as this may cause irritation to the legs.



  • Designed to fit babies approximately 4-18kg
  • 3x4 adjustable rise snaps
  • Cross-over snaps to fit a smaller waist size


  • 1 x 5-layer hemp insert
  • 1 x 5-layer bamboo insert
  • 1 x 3-layer bamboo ("Nap") insert

Great for Nights!

i was looking for a new night diapering system and decided to give this a go! We now have a bullet proof system with the hemp insert, 5-layer bamboo insert and the nap insert. That setup supposedly holds almost 700ml of fluids! I am slightly disappointed with the quality, some of the nap inserts is a little torn at the seams after just max 5 washes. But i still went ahead and made this my main system because it works. Note that the hemp inserts do take a while to dry.
