Grovia BIG O.N.E


Nappy Overview

The GroVia BIG O.N.E is designed for children who have outgrown their popular onesize O.N.E   The O.N.E range are entirely different to any other nappy made as it offers two built-in fastening options, Aplix and Poppers so you have the choice to use either fastening.  The removable Aplix/Hook & Loop closure is perfect for those who love a “no-hassle” fit but want to transition to a snap closure later on. The Aplix can also be easily replaced with the use of GroVia replacement Aplix Kit if it shows signs of wear and tear. The Aplix is VERY strong offering a very secure fastening that won't come undone however because it's so strong it can be a little fiddly to open the nappy when changing baby. Ideal if one parent likes Aplix and one prefers poppers!

So what does O.N.E stands for?
O - Outlast Closure
N - No Prep
E - Easy To Use

The GroVia BIG O.N.E comes with 2 inserts included in the nappy a large pad that is your main absorbency and a smaller pad which poppers onto the main pad so you can add more absorbency later on as baby gets bigger. The main insert has channelling stitched into the pad to help guide liquid into the core of the insert.  There is also a hidden layer of absorbency underneath the interior fleece of the cover. This is hidden away and helps to prevent wicking and leaks.


The Grovia BIG O.N.E fits from approximately 35-70 lbs with adjustable absorbency.  This is a very large nappy which is very generous in length and size. It is definitely not a slim choice and is best for chunky monkeys.

How do I use it?

The GroVia BIG O.N.E is an all in one nappy so works just like a disposable nappy in that you take off a soiled nappy and replace with another clean one.  As the inserts have a polyester microfleece topping you don't have to use a separate liner in the nappy however you can use a separate paper liner if you prefer for ease of use, The Bambinex paper liner fits perfectly.

GroVia BIG O.N.E is a onesize nappy and is altered by the standard options of poppers on the body of the nappy to shorten the length and by an adjustable waist

Nappy Fabric

There are two types of Grovia BIG O.N.E, Original and the Buttah. The inside construction of both nappies are the same. The difference however is with the outside, the Original is made with waterproof TPU but the Buttah range instead uses proprietary Laminated Polyester Velour. The Buttah outer is shimmery, pillowy and possible the softest thing you've ever touched. The Buttah range is slightly more expensive due to the premium outer.

Inner Materials:
Hidden Inner Layer: 100% Polyester Microfiber
Soaker: 100% Cotton topped with 100% Polyester Microfleece
Body Lining: 100% Polyester Microfleece

GroVia Care Guide

  • Prewash nappy twice before first use.

  • No harsh stain removers or bleach. They may cause irritation and can damage the waterproof membrane
  • Close any hook and loop fastens before washing
  • Add a full dose of detergent into your machine.
  • Detergent must not contain whiteners, dyes, perfumes, essential oils or natural soap
