Throughout the years I have been using cloth diapers, I have done some experimentation to find the best all-in-one cloth diaper. The Blueberry Simplex meet that standard for me, and I just love them!

All-in-ones are one of the most convenient styles of cloth diapers. They are the easiest style to convince apprehensive spouses or caregivers to use. I also find all-in-ones to be one of the most impressive diapers to show off to cloth diaper naysayers.

There are several brands out there, and when it comes to the best all-in-one (or any style of diaper), it really boils down to personal preference based on which features are important to you. It’s possible that not every single family in the cloth diaper community would agree with me that the Blueberry Simplex is the best all-in-one diaper because for whatever reason, some families probably found a fit they prefer in a different brand. However, there are many families who share my views of the Simplex being one of the best, if not THE best, all-in-one diaper available, and for good reason.

How is the Fit? What Is It Made of?

blueberry-simplexThe Blueberry Simplex is a one-size diaper best fitting babies between 10-35 lbs. The waist measurements best fit a baby that measures between 9 and 21 inches around, and the thigh measurements it works best for are between 4-12.5 inches.

The outer layer of this diaper is waterproof, while the inner absorbent part of the diaper is made from 10 layers of 100% cotton. This is a unique all-in-one because it has openings on each end that allow you to stuff another insert (much like a pocket) if you need extra absorbency. This diaper is able to be customized for absorbency so much more than any other all-in-one that I have seen. That’s one reason why I love it so much!

The inner soaker also has a layer of microfleece that you can use for moisture-wicking purposes.

There is a flap insert soaker that has a layer of microfleece that is only sewn on one end of the diaper. You can fold the insert to the inside the diaper if you prefer your baby’s skin to only touch natural fibers, or it can be laid over the top of the middle cotton soaker area as a moisture-wicking layer (which is usually what I do). The flap agitates out all on its own in the wash, so you do not need to unfold it before putting in the diaper bin. The flap only being sewn to one end of the diaper also improves drying time, which is a concern for many kinds of all-in-ones. Above is a snapshot from the Blueberry website about some of the cool features of the diaper.

This diaper has a wide assortment of prints available. Anyone can find a print they absolutely adore. They will even have some specialty prints around holidays (but prepare to pay more for those).

Who Is It For?

This is a great all-in-one for someone looking for a soft and flexible fit for their baby and prefers to use a mix of natural and synthetic fibers. You have the option to allow 100% cotton to touch baby’s skin if you wish, but if your baby out-wets the materials, this diaper allows you to stuff more inserts into the pocket area while still having the option to keep the cotton against the skin.

If natural fibers touching the skin isn’t as important to you, you have the option of the microfleece liner on the soaker pad to help wick moisture away to create a stay-dry feel, and you still have the benefit of being able to stuff the pocket area with even more absorbent inserts!

It has a nice, trim fit for families worried about too much bulk under baby clothes. It also has a multitude of adorable prints available.

Who Is It Not For?

This diaper would not be for a family that doesn’t like all-in-ones. Some families just really don’t enjoy all-in-one style diapers and prefer other systems. If that is you, I wouldn’t invest in any Simplex.

Also, some people with heavy-wetter babies want more absorbency than cotton provides. You can still stuff the Simplex with extra soakers/inserts, but if you don’t want the hassle of that, then you may need to look into other diapers with a more absorbent inner material, such as hemp or bamboo. However, prepare to pay more for those.

What Does It Cost?

As far as all-in-ones go, this one is priced on the higher side. Certain prints may cost more, but other prints cost less. This diaper is typically priced in the mid $30s. This may be more expensive than most families are looking for.

Get A Few of These for Your Stash!

While you may have plenty of other diapers you want to get, I highly recommend getting at least two or three of the Blueberry Simplex All-in-Ones in your stash because they really are such a great diaper. I know you will not regret investing in them! They are cute, soft, comfy, and so easy to use. They have long been one of my favorite diapers, and they are definitely my favorite all-in-one diaper. They have held up well over the years and have been used on both my children. All the seams and elastic have held up so well!

    As a grandparent with a new grand baby I am really starting to enjoy this website.  I am trying to talk the kids into using some of these diapers.  I think it would be fun to have different themed diapers.  Once again I am going to send them the link.  I’m sure if I send it enough times they will get the hint.  Thank you for doing such a great job on this website.

      Thanks so much, Dale! I love that you keep coming back. 🙂 The Blueberry Simplex is an awesome diaper!


    These diapers look very stylish, I have a question. Do they function like the ordinary diapers, where you use once and throw it away? Or with all the new designs implemented, there is a way of recycling a diaper and using it for the second time?

    I visited the link to the sample you included in your post. $26.32 the price for 1 diaper, or the price for a packet of diapers?

      Hello! Yes, you definitely use them again–that’s one of the goals of cloth diapers. 🙂 They can be more economical than disposables and better for the environment! Here are some posts that might help you learn a little more: Pros and Cons of Cloth Diapers and Pros of Cloth Diapers. Hope this helps–shoot me a message if you have any more questions, I’d love to help!

      Also, that is the price for one diaper, but it can be used over and over for several years.

    Hi Holly,

    These are some interesting diapers. I love the colors, design, different textures and that it is 100% cotton. I’m not a parent still so I wouldn’t know to say for sure, but I would buy some of these for my kid. It depends if the child would need more changing or less. I like that they are natural, because that is very important for the baby. My friends just got their first kid 2 months ago, so I will show this to them. I think they will be thrilled. 🙂

      Glad you found it helpful! You do have to change a little more often with cloth (every 2-3 hours or so as opposed to 3-4 hours in a disposable), though I really believe that kids should be changed more often than every 3-4 hours even if they are in a disposable. A disposable does not allow for as much air flow, and it’s not very good for the skin. So just because you CAN go 3-4 hours in a disposable doesn’t mean you SHOULD, if you know what I mean. 🙂

      Even when my son wears disposables for whatever reason (traveling, etc.) I find he needs to be changed on the same schedule anyway, so I think the amount of difference in time really isn’t that great of a difference.
