Trima AIO - Brick

The Trima is Petite Crown’s signature all-in-one diaper with lining and inserts made fully of natural fibres. It comes with two removable 3-layer inserts that can be snapped onto the shell easily — perfect for those who find stuffing inserts fiddly and inconvenient. There is also a pocket opening for extra absorbency, so it can even be used as a night nappy! The Trima will cater to the changing needs of your growing child by allowing you to customise the absorbency effortlessly.

Why we love it

1. Versatile yet absorbent

The Trima comes with two removable snap-on inserts, and you can choose to snap one or both, depending on your child's needs. The shell is lined with buttery soft bamboo cotton, providing an additional layer of absorbency. You can also add additional absorbency into the pocket for heavy nap wetters or for night use. It is so versatile that you only need the Trima in your stash for all the different needs of your child!

2. Easy laundry

The snap-on inserts make the Trima super easy to prepare after a long week, so you won't end up buried under a mountain of laundry. The removable inserts allow for far easy cleaning/spraying, as well as faster drying time compared to conventional all-in-one diapers. 

3. Leak protection

The luxuriously soft bamboo cotton lining will catch any leaks, so you don't have to worry even if you have a 'flooder' baby. At the front of the diaper, the PUL tummy panel offers extra leak protection and prevents pee from wicking onto bub’s shirt. The wide but firm elastic at the back of the diaper ensures that all poop is contained within the diaper, without being too harsh on bub’s skin.
