This contains the cloth diaper as well as the cover

I ordered this thinking it was just a cover, not an all in one diaper. It has the cloth diaper attached and can’t be used for separate cloth diapers. I didn’t read the description correctly. The ones star is because it wasn’t what I was expecting.I returned it and Amazon were prompt at refunding my money. Love Amazon returns!!!

night diaper

We use this as our night diaper, with an additional insert, and a thirsties diaper cover. Yes, we also are disappointed that this diaper is missing the double gussets, but the covers have them, so we are ok.One star off for lack of double gusset, and the other star off for misleading sizing. I would say the size 1 fits up to 15 pounds, and size 2 can fit as small as 14 pounds. I switched from size one to two when my baby began weighing 14.25lbs. This is one of the only diapers left that has the main pad sewn-in, which I like. just remember to turn it inside-out when going from washer to dryer.

Great product, but dont do velcro

The velcro is so convenient and nice, until you wash it. It attracts fuzz, hair, and the velcro warps. The button top All in Ones by thirsties look like a bigger pain, but they arent. With the velcro, you have to worry about warping, ripping, and it eventually not sticking well enough. Velcro thristies only fit my son up to 16.5 pounds, but the button top size ones fit my son up to 18 pounds like it says, and he is a big boy. at 18lbs and 25 inches long, I was afraid I would have to buy size 2 by 15lbs, but not with the button tops.On another note, thirsties all in ones are super convenient and easy. Great product, few leaks. Change your baby ever 2-3 hours and leaks are almost never an issue. After a few months use, if you start to smell bad smells, or notice less absorbancy, just "strip them." you can find how to very easily do this on google or youtube.I love my CDs. (except at night, then I use a disposable overnight, and a thirsties duo wrap to prevent blow outs).

Some leaks but easy to use

I like Thirsties products so I tried the AIO but have found that they do leak quicker than my prefolds and cover systems. I have added newborn prefolds to this AIO to increase absorbency but find it quite bulky. I still like to use them during the day when my daughter is active and is getting her diaper changed more frequently than nap time and night time. I also like to use them in my diaper bag so when I am out the AIO makes a quick diaper change time. Nice convenient AIO if you are not in need of something super absorbent.

I guess I will address the elephant in the room

Sooooooo… first off I love Thirsties and out of all the reusable diapers I have tried I chose Thirsties Duo Wrap and inserts. I have been using them for over a year and plan to continue until my baby is potty trained. They have held up due to great construction and I doubt I will have to replace them before potty training time comes.Back to this diaper – the Duo All in One size 2I think the fact that it has been out for many many weeks and not one single review says it all! Thirsties has very loyal customers and we don’t want to say anything bad about them but we are not happy with this new version when the previous version (Duo Wrap) is so incredible!!!The Good: (which by the way is in all Thirsties products with the exception of #7)1. Incredible construction of the product. Seems are perfectly aligned, strong, and sturdy2. Made in the USA (this is above all the best thing)3. The length of life this diaper cover has. Only two sizes to hassle with unlike many many many others that have 5 or more from birth to potty training. Thirsties has 2 sizes and that is it!4. The material is water proof, strong with good stretch for comfort for a crawler5. I love the velcro top, it is just like using a disposable diaper6. The patterns are so cute and such a variety7. The sewn in diaper liner is sewn just in the middle areas to provide easy cleaning and drying8. Safe for washer and dryer :)9. The material outer material is also breathable and I have yet to have diaper rash on my little girls bottom ever since using Thirsties.The Bad: (sorry Thirsties)1. Where are the leg gussets?????? This is the biggest reason for the bad rating for me… the leaking I have is occurring through the leg area. The binding is nice and tight (not too tight) but the binding seam absorbs wetness and then leaks onto the clothes from there. If I do not get to the diaper the second she goes potty it is over… I end up changing the diaper cover since the leg area is wet, the diaper liner itself (of course), and then all the clothes!2. The sewn in liner is great but holds nothing for my little 15mth old. She over fills that in one pee pee (meaning before she is even done going potty it is leaking), so I started using my Thirsties hemp inserts and that helped as far as absorbing but back to #1 the leg outer seam just soaks it all up from the liner then then transports it to the clothes. For those who want to try this option, you can slide your hemp insert behind the soft top sewn in liner. That way the soft liner is against bottom!Sorry Thirsties but I am sending this one back. I LOVE LOVE LOVE the Thirsties Duo Wrap and Hemp inserts and will be sticking with those until diapers are no longer needed.See my other reviews to find the Thirsties Duo Wrap and liners that I use and love 🙂 By the way for little little ones that would wear size 1, this AIO diaper may be perfect… but my 15mth old just produces too much for it to hold without leg gussets.Ideas on how to improve would be adding the leg gussets… that would make this a perfect AIO!

The diaper I grab first!

I am now diapering my 4th baby. I’ve used every type of diaper out there in the past, and while they are all great, and have their own merits, right now I’m just plain busy and don’t have time to be stuffing pocket diapers every two days, or folding prefolds on a crying squirming baby. I just want something that goes on as quickly as a disposable (which pockets do as well)–but that you can wash, dry, and toss in a drawer and be done with it, no prep work involved. Simple! They’re absorbent and keep your baby dry due to the soft microfiber. I’ve only had a leak once after my daughter took a long 3 hour nap and soaked it. Normally, during the day she can wear one 2-3 hours no problem. I’ve pushed the rest of my diaper stash to the back of the drawer, and purchased 12 of these, using them almost exclusively now.

This diaper works, but I just don’t like it very much. I prefer any BG diaper over this one, but I do love Thirsties fitted diapers and covers.

Aline Cornish, UT

Favorite Brand but one downside

I love these diapers. The covers are my brand of choice so I decided to try these all in ones. Perfect for my 2 1/2 month old with enough space to add inserts if and when she needs more absorbency. The only downside is the velcro, it comes undone sometimes if she is kicking her legs. I LOVE all the choices in patterns and colors and they fit perfectly! Our girl is longer than most for her age so the adjustable length is awesome. Will continue buying and just be extra careful with the velcro.

Lillie South Carver, MA

Not the usual trustworthy Thirsties performance.

Love the brand, but these did not perform as expected. Soaker was too short in front (bad news for a boy). PUL leaked through the stitching. Otherwise, love the fit and design. Maybe just a faulty batch . . .

Mable Avenel, NJ


Not a huge fan of the Thirsties all in one diapers….I love their covers because the double gussets hold wet and dirty diapers well…but these don’t have the double gussets so they leak every time my heavy wetter son pees.

Lora Clinton, OH

Great diaper but tight waistband

I really love the Thirsties AIO for few reasons: Trim-smaller than other brands (exceptgdiapers) and not bulky under her clothesEasy to get on-we have a wiggly newborn thesego in just fast as disposablesGreat absorbency- I’ve used these for nighttimediapers on our baby from 2 weeks old, shesleeps up to 6 hours at nightEasy to clean-no picky washing routine needed Just put on warm with good cloth detergent,extra rinse cycle (I turn them inside out first)Cute designs and colorsThe only drawback is that the waist and thigh bands leave red marks/indentions on my little one. I tried loosing to the biggest setting and still indentions in on baby’s back even though the front is loose. The ted marks on bay’s legs may be due to thicker thighs (the gDiapers gussets do the same)I really love these diapers just don’t like that they leave marks. I haven’t seen anyone say anything about this on their reviews so I wanted to mention it. I hear that some babies are sensitive to clothing that touches closer to the skin but Im not sure they just seemed to tight so I purchasing the next size (size 2) to try. If your wondering she is 9 lbs 15 oz and we are using the last settings

Good if you add a doubler

I love thirsties products. I absolutely LOVE their fitteds so I figured I’d try this to save myself a step. First time I used it it leaked 🙁 So I added a hemp doubler and it works perfectly. It’s the only diaper I have with aplix which is easy but I do prefer snaps for their longevity.

Charity Saratoga, WY

like the AIO, not the velcro

This is our first adventure in cloth diapering. After copious amounts of research, we decided to start with this brand. I purchased prefolds, the duo cover, a duo fab fitted, stay dry inserts, the duo AIOs, and the wipes, all from Thirsties. The AIO has been the easiest to use. My husband has no complaints about these versus disposables (and I’m shocked). These wash well, don’t stain, dry in about 1 1/2 cycles in the dryer on medium (not too bad). The snaps hold up well to both my 2 month old and my 2 year old who wears them to bed. I haven’t used them with a liner yet. I do recommend the snaps over the velcro though. The velcro doesn’t hold up well in the wash after only a few weeks, and I’ve been careful with it. Also, one of my other diapers arrived with a damaged snap (still functional but cracked). Thirsties customer service immediately sent out a replacement and postage paid return for the damaged one. Great customer service is a great bonus. Everything arrives in eco friendly packaging and is made in the USA.

Mina Lakeside Marblehead, OH

Almost perfect….

They are very easy since they are AIO’s. My husband loves these since he doesn’t have to think about what to stuff in the pocket since there isn’t one. But they take a really long time to dry.

Diane Lucien, OK

They work

The way the inserts are sewn in makes them take forever to dry. I usually have to kind of flip them inside out to dry them faster. They are a bit thick, but they are more narrow in the crotch and fit my tiny girl well. I would have bought snaps if I could do over, though. The aplix is easier but sometimes rolls inward toward her belly and irritates her skin.

Joanne Coyle, OK

Inexpensive All-in-One diaper

What I love the most about this diaper is the price. $15 for an all-in-one diaper that is made in the US is amazing.The aplix is good and strong and the colors I chose (meadow and orchid) are very pretty. The construction is a lot more solid than I was anticipating, some of the photos of this diaper make it appear cheaply made but it is not! The materials are top notch!It does take a while to line dry inside, it took about 10 hours or so. But outside in the sun (and I live in the Pacific Northwest so its not like we have 100 degree heat or anything) it took 3 hours to dry. So not too shabby.The only thing I don’t like about this diaper is that the absorbent layers are micro fiber. I do not like micro fiber. And this is one reason why I don’t buy too many all-in-ones because I don’t like to be stuck with whatever is sewn into a diaper. But I like that this has the "tunnel" feature, so I can add whatever absorbent layer I choose later when the micro fiber starts to fail (which it eventually will). Something that would make this diaper exponentially better is if Thirsties added their wonderful hemp/cotton jersey in place of the micro fiber. I realize this would make this a less affordable option but it would make a FAR superior diaper that would have a longer lifespan.But this is a great option for families on a budget that want the ease of an all-in-one diaper. I would highly recommend it!

Adriana Lothian, MD

Up to 40lbs my rear end.

My baby weighs about 23lbs and this barely fits her now. I knew when I first put it on her at 12lbs that it would not fit her at 40. Also, all her other diapers are pockets, and this one is the only one that leaks within an hour. So, it always needs a 2nd insert, even if it isn’t overnight, and even when she was only 4 months old and not a heavy wetter. I go for this diaper last out of all my cloth. I do LOVE the Velcro, though. But the color is a tad more yellow than pictured.

Therese Mammoth Lakes, CA

no red flags, but personally prefer bumgenius

This was my top pick for cloth diaper BEFORE having a baby. She is now 11 weeks old. I also tried fuzzibunz and bumgenius 4.0, and we decided to go with bumgenius.The Thirsties Duo is not a bad diaper. It’s well made but the fit is not great for my little girl. It irritates her and leaves red marks around the gussets. I use this diaper only when I know she won’t be in it long enough to bother her.I have no problems with leaking, it washes up well, and is the least bulky of the three that I have tried.This is NOT a problem with Thiristies but with all-in-one cloth diapers in general: although I read the warning before purchasing, I was still surprised by how long it took to dry. It just wasn’t practical for us. Keep that in mind when deciding which type is right for you. 🙂

Erna Darlington, WI

Best diaper ever!!!

I love love love this diaper. It’s perfect!!! I have used several different brands and this is by far my favorite. A lot of the OS diapers were to big for my LO so I love that this one comes in two sizes. The colors are pretty plus I hate stuffing the pocket diapers. I use just the AIO during the day and only need extra padding during the night.

Rebecca Phoenix, OR

Great for skinny/small babies!

I used this as my nighttime diaper for a while, stuffed with another insert. I LOVE the design of the diaper with the “tunnel” thing. It’s simple to use, easy to put another insert in it, fits great on my little baby, and looks cute. However, it does take forever to dry, and the aplix isn’t the best, as it frays after a month or so of washing regardless of using the laundry tabs.Overall its amazing, and I’d buy a whole stash of these if it was more economical to do so. Having to buy two sizes at $16 a piece is more than I’d like to spend.

Brittney Mapaville, MO

daytime only

This was the leaky-est diaper we had. Sad, because it looked so cute & I really wanted to love it. I don’t know if it was design or just capacity. Our Thirsties pockets are much more reliable.

Phyllis Donner, LA

MY Favorite

I bought a bunch of different brands of AIOS to test out to see which ones I like. These are my favorite! Very absorbent and a true AIO, no stuffing pockets, drying time is a little longer, but it is a very good diaper!

Lauri Vienna, IL

Soaker not long enough in front for boys

Like the diaper, but definitely runs smaller than manufacturer suggests. My baby was out of this at 13 lbs. May have stayed in snap closure longer, but velcro didn’t stay closed when he became big enough to really wiggle. Had a couple leaks since the soaker doesn’t come up high enough in front at all for a boy. Had to change him quickly even with an added insert. Might have been ok for a girl.

Harriett Salina, PA

Takes a long time to dry.

This diaper was my favorite when I first ordered a variety of cloth diapers due to it’s ease of use. The only reason i’m giving it 4 stars is because it takes so long to dry. It has a slim fit for a long and lean baby. I like that it is an AIO, but that you can also stuff like a pocket for super absorbency.

Dora Livingston, IL

Great Purchase!

I purchased several of these diapers in various colors. My baby is at the low end of the weight range for size 2 (18 lbs). The inside of the diaper feels like the inside of a new sweatshirt-so soft! The patterns are very cute, and the solid colors are ok (don’t likethe pink-too neon by itself). I bought velcro, and they hold up nicely in my front-loading washer. I hang them to dry in the sun, and the stains are out in no time. Haven’t had a blowout in them yet, and there is a pocket for a night time doubler. They are quite large, so I am hoping they will make it to potty training for my big girl (she is only 6 months, but at 95th percentile for height/weight).

Awesome at First But Quit Using Due to Stink

OK! This is the best fitting diaper for a thin baby I’ve ever found. I found it to be quite trim as far as cloth diapers go, and it looked adorable. Unfortunately though, after a few months of using these I could not get the stink out. I tried every remedy as an experienced cloth diapering mom, and just couldn’t get the urine smell to come out. I think it’s because it is incredibly difficult to get this diaper dry all the way through, and to clean it all the way through its many layers. This is why after years of trying both cotton and synthetic diapering systems, I have to vote in favor of a cotton or other natural prefold of some kind, and a cover. Prefolds wash easily, dry easily, sun-bleach easily, and last forever… synthetic fibers just don’t do any of those things…

Edna Hopewell, VA

Sizing is off

It’s super cute, and fits great, but already barely fits my 14 pound baby. I love how the built in soaker doesn’t go all the way to the front of the diaper so when you snap down the rise snaps there’s no bulk. But, this means the soaker barely covers my son’s privates because it’s so small. I wish it was true to size because otherwise I love this diaper.
