Absorbency testing is huge in the cloth diaper space because everyone is curious about a product’s ability to perform and whether it’s worth the cost or the investment or the cheapness of the product. There are a variety of prefolds, preflats, flats, rectangle inserts and other larger absorbency options on the market. This post is dedicated to them to help keep it simple with regards to learning about the absorbency of products.

You can check out my YouTube Channel to see and watch videos related to absorbency testing of many these products. 

How I Absorbency Test?

I’m measuring the maximum capacity of an insert by soaking it in water and then measuring the weight of the insert minus the original weight. This is explained in the video below. Maximum capacity and everyday real life experiences will vary. The key is about consistency. I’m also verifying all of my results by measuring each product at least three times to come up with an average absorbency of the flat or the prefold or the other large insert type thing. 

There are many ways to meausre absorbency and it’s not consistent across the board. Be sure to consider those variations when reflecting on numbers. Mine is really max capacity after one minute. I have not found longer soaks to actually increase absorbency textiles like bamboo or hemp but this may evolve with time. 

Check out this playlist to hear me talk about the absorbencies as well as to see many of these do a pour over test and you can see just how well it does absorb (or doesn’t absorb)

Absorbency of Prefolds

Remember bigger isn’t better, and the most absorbency isn’t the answer too your needs. That top Osocozy Prefold is a crazy big size and never something I’d use on my child. I would much prefer doubling the Nuggles Inserts to get to 22 ounces as it is much trimmer and smaller fit. These products exist to fill a need but dont’ forget to look at the size of your baby and the amount of absorbency you actually need.
