Product Description


Bumgenius 4.0

Stay-dry, one-size pocket nappy.

Bumgenius One Size nappy - Twilight

BumGenius nappies have become a popular choice in recent years. They are highly adjustable, and give a neat fit from birth to potty training (approx. 8lb - 35lb/3.6kg - 15.9kg).

BumGenius one-size have a built in waterproof outer cover and an inner lining, which form a pocket. The outer PUL cover keeps wetness and moisture in, whilst the inner lining is made from suedecloth (a soft polyester knitted fabric) and helps to keep baby's skin dry and comfy. At the back of the pocket there is an opening into which absorbent pads (supplied with the nappies) are placed. The level of absorbency can therefore be customised to suit the baby and the occasion.

Stretchy lycra wings make the bumGenius nappy unique among pocket nappies. They enable the nappy to be pulled close all around baby, and this ensures a really neat fit. Bumgenius V4 fasten either with hook and loop or poppers. The hook and loop version has laundry taps to fasten the tabs to reduce the hooks catching in the wash.

The size of the nappy can be easily adjusted through a system of poppers on the front of the nappy. The height of the nappy is shortened using three columns of snaps to enable it to fit small babies from 7lbs. BumGenius nappies have a slim elasticated leg casing and are elasticated at the back to keep everything in.

The bumGenius V4 is the latest version of this nappy, and the new features include a more generous sized fitting to enable the nappy to give a better fit at the higher end of the weight range.

Bumgenius One Size nappy - Yellow


These nappies come in just one size and are so adjustable that you can get a good fit for the majority of babies most of the time from around 8-35lb.


As already mentioned, you can choose to have your bumGenius with a hook and loop or poppers fastening. There are advantages to each type. The hook and loop are very quick and simple to fasten, and are a good for nurseries or those who are used to disposables. However, some people find they reduce the nappy's durability due to the hook and loop wearing out and snagging the outer layer. Hook and loop fastenings can also be easily removed by toddlers if they get a taste for freedom! Poppers/snap fastenings take a few seconds more to fasten and are slightly less straight-forward for those unused to cloth nappies, but without the disadvantages mentioned above.

The bumGenius one-size pocket nappy is available in a range of attractive colours: Blossom, Bubble, Butternut, Grasshopper, Noodle, Sweet, Twilight, White. Please have a look above for all colour and print images.

Advantages & disadvantages

bumGenius V4 over other one-size nappies. One-size-fits-most and works out as an economical choice. Lightweight and quick drying. Good adjustability and very neat fit. Choice of poppers or hook and loop fastenings. As with all one-size nappies, bumGenius may be outgrown sooner than potty training on larger or stocky toddlers.

Suggested inserts

The bumGenius V4 comes complete with two microterry inserts. Boosters will not usually be required for day time use. Some babies may require additional absorbency for night times. We recommend you use a microterry insert (supplied) with a hemp or cotton insert underneath. Have a look at our cloth nappy inserts if you want to purchase one.

What else will I need?

Nothing else is essential to use this system, though flushable liners can make solids disposal easier and it will be helpful to have a tight-sealing bucket or bag to store the nappies in.

Second hand value



Ensure laundry tabs are fastened on the hook and loop version Bumgenius. Machine wash at 40ºC (or up to 60ºC if required). Hang to dry or tumble dried on low heat if preferred. Do not use greasy rash cream. Click for more information on the care of Bumgenius nappies.
