Natural Fleece Baby Pajamas

When I stopped swaddling my son, I needed to find very warm natural fleece baby pajamas for him very quickly.  The first time I did not swaddle him, I put cotton pajamas and a cotton sleep sack on him instead.  To this day I remember vividly how icy cold his little hands were when I got up in the middle of the night to nurse him.  I was not going to make that mistake again and looked frantically for very warm natural fleece baby pajamas.

To my dismay, I quickly learned that in this modern world, “fleece” equals “polyester.”  I did not want to buy polyester fleece baby pajamas for multiple reasons.

Why I did not want polyester fleece baby pajamas

First of all, polyester pajamas for winter do not do a great job of regulating body temperature, and so they may overheat your baby.

Secondly, pajamas that are not natural fleece baby pajamas are not breathable.

Moreover, polyester fabric is likely to contain flame retardant chemicals; more on this below.  Also, it may contain other undisclosed toxic chemicals such as formaldehyde.

On top of that, most polyester is made from petroleum, which is an unsustainable resource.

Finally, polyester fleece baby pajamas shed microfibers during each wash.  These microfibers travel to your local wastewater treatment plant where up to 40% of them enter rivers, lakes, and oceans.  The microfibers are particularly dangerous because they have the potential to poison the food chain.  In one study, human-made debris recovered from fish in the US consisted primarily of microfibers.

Flame retardants in children pajamas

Let’s briefly talk about flame retardant chemicals and why they are in baby pajamas.  

In the 1970s, the Federal Government adopted a flammability standard.  It required pajamas for kids between 9 months and 14 years old to withstand a 3-second open flame test without igniting.  Many baby pajamas manufacturers added brominated tris flame retardant – up to 10% of the fabric’s weight – to make sure that their products passed the flammability test.  

Two Green Science Policy Institute scientists, Arlene Blum and Bruce Ames, published the results of their research into brominated tris.  They discovered scientific evidence that this flame-retardant chemical was a DNA mutagen and carcinogen.  As a result of their research, brominated tris was banned from children pajamas in 1978.

Chlorinated tris replaced brominated tris, but it was eventually phased out, too.  Thus, chlorinated tris and PBDE are not used anymore due to health concerns.  However, other supposedly less toxic flame retardants are currently in use.

Sadly, there is no requirement in any state (even in California) to disclose flame retardant chemicals used to treat baby pajamas.

What options are there for natural fleece baby pajamas?

While I was searching for natural fleece baby pajamas, I came across a wool sleep sack on Amazon.  The sleep sack is no longer available but it looked similar to this one.

I did not like it that much – it was not soft enough.  I do not recommend it now because babies can have allergies to wool if it touches their skin.

At some point, I bought Cosilana organic wool pajamas, but they were also not soft enough.  Plus, the legs were short, and when washed with warm water, the pajamas shrank.

After a very long and frustrating search, I found natural fleece baby pajamas that I liked a lot.  They were so soft and fuzzy inside.  However, they were discontinued soon afterwards.  You can’t buy them now, but I have a picture of them.

I also tried organic pajamas by Snug Organics.  They were very warm and well-made.  But they were a little too snug fitted, had no feet, and shrank when I put them in the dryer.

Fortunately, I was able to find the perfect thing; keep reading.

The warmest organic sleep sack

Before we get to the perfect thing I promised, I want to talk about sleep sacks.  Even with warm natural fleece baby pajamas, I needed a warm sleep sack.  After trying a few different sacks, I found the warmest cotton sleep sack by Ergo Pouch.

Made like a quilted blanket with organic cotton filling, it was very warm.  The product description said that it was designed to keep a baby warm at temperatures as low as 57F.  I didn’t think that my son would still be warm at that temperature; maybe if he would have had a hat and gloves on.

Ergo Pouch is an Australian company, and if you buy from them directly, shipping is very expensive.  However, from time to time they sell on Amazon.  That was where I bought their sleep sack.  It was a lifesaver.  It was a nice addition to our natural fleece baby pajamas.

This organic sleep sack comes in two sizes: 2 months-12 months, and 12 months -3 years.  It means that you will only need to buy it twice. 

Organic sleepwear by Castleware

OK, now we can talk about the perfect product I mentioned above.

When my son was about 2 years old, one of my blog readers asked me if I could recommend a sleep sack with foot holes.  In my search for one, I stumbled upon Castleware organic sleepwear.  Read my reviews of their wearable blanket, their best organic cotton pajamas, and their fleece footed pajamas.  You can also check out the Castleware baby sleepwear options in my shop

Since then, Castleware has become my favorite brand.  It is a true brand of luxury – every item is impeccable.  They now make organic pajamas and wearable blankets in three fabrics: rib-knit, fleece, and velour.

Castleware fabrics and manufacturing process

All Castleware products, including fleece baby pajamas, are made of 100% organic cotton yarn.  And the dyes meet the requirements of  OEKO Tex 100 standard.  It limits or bans 100 harmful substances.

Castleware is an all-American business.  The organic cotton comes from Texas.  Spinning and knitting are done in South Carolina and the sewing is done in California.

Castleware cotton pajamas cut and sizing

The natural fleece baby pajamas by Castleware remind me of a lot of the first fleece baby pajamas that I found which were discontinued later.  The fabric is the same, but the cut is better.  The legs are longer and sized more generously.  This is such a big plus!  My son was quite a tall baby, and I had a problem finding cotton pajamas for boys his height.

In fact, my blog followers loved Castleware products so much that it motivated Maureen, the owner of the business, to introduce changes.  She started making natural fleece baby pajamas in sizes 5T and 6T as well as enlarged her assortment of colors and fabrics.  It feels so great to be able to contribute to expanding a small business with all the stages of production in the US.

  1. I was just wondering what kind of pjs you plan to get your baby now that he’s outgrown sleep sacks. I’ve been looking for something warm for my 16 month old. Seems like there are only 2 or 3 super pricey options available.

    Thanks.

  2. Very excited to find your blog. Reading labels is so much work, its nice to find more resources to help with this monumental task when trying to buy things safe for your kids and the environment. To answer the one posters question; as my kids have gotten older, I just buy organic cotton pajamas. I find that even here on the east coast, my kids don’t want to sleep with blankets and those keep them plenty warm. I buy all my cotton PJs off of Greenbabybargains.com. Every so often they have organic pjs on sale and its the only way I can afford them. And as long as they don’t eat breakfast in them they last at least two nights so I only need to buy a few pairs per child. I’ve purchased from three different companies and have been very pleased with the; they are all high quality, thick and sturdy snug pajamas.

  3. Irina,
    I have recently learned how cruelly animals are treated whether it’s sheep for their wool, duck for their feathers, cows for their leather and so on. These animals suffer so much and are abused and treated horribly by the people who handle them. I no longer purchase anything that comes from an animal. I wasn’t sure if you’re aware of this and just ask to look into it and possibly reconsider suggesting wool or other products that come from animals.
    PETA has a lot information and videos. I cannot watch these videos and can barely look at the pictures as they are very disturbing.
    Thanks so much,
    Suzie

  4. Chemicals are also a serious concern to me, but in this era of international trade, I find it easy to go around: I buy my sleepwear from non-US sources (as an example and being French: say, from ebay.fr with keyword “pyjama”), to ensure healthier options. Note that a lot of “safe” options in the US (pajamas, sleep sacks, etc…) still contain chemical treatment. If a label has an elusive “garment has not been treated” (a.k.a. dipped into chemical), it remains that its fibers might still have been treated (fiber treatment is supposedly less hazardous than garment’s) to pass the flammability test. Kind thoughts. E.

  5. I am curious if you have heard anything about Halo Sleepsacks. According to their website FAQ regarding this issue, they state:

    “Is the HALO SleepSack wearable blanket chemically treated with flame retardant chemicals?
    NO. The fabric and fibers used to make our garments are not chemically treated in any way.”

    http://www.halosleep.com/frequently-asked-questions/

    True, or have you researched otherwise?

    Thanks!

    1. Hi, Wendy: Baby sleep sacks are considered bedding and thus do not have to meet the federal flame retardant standard (16 C.F.R. Parts 1615 and 1616) as baby pajamas do. However, polyester sleep sacks might still have flame retardant chemicals built into polyester fabric during the manufacture of the polyester fabric. Therefore, if you ask the sellers whether their polyester sleep sacks are treated with flame retardant chemicals, they may tell you “no” and they may be right, but this does not ensure that the sacks are truly flame-retardant free. I believe Halo sleepsacks are made of cotton. Is that correct? ~Irina

      1. Hi Irina. Thanks for your reply!

        That is interesting that they’re considered bedding. The child still wears them !! 🙂

        Not all Halo Sleepsacks are cotton. Some of them are 100% polyester micro-fleece
        http://www.halosleep.com/halo-sleepsack-early-walker-micro-fleece-pink-butterfly-ombre/

        Because of the fact that their FAQ states that the fabric AND FIBERS in “our garments” are not chemically treated, it leads the reader to believe that none of their sleepsacks have flame retardants. Hopefully that is not just wordsmithing in some way 🙂

        1. Hi, Wendy: I know polyester is so tricky. We are not told what is really in it. We can only make educated guesses. Are you considering buying their cotton or polyester sleep sack? I have some favorites… My baby is 4 years old now but I still remember the time I was desperately looking for sleepware to keep him warm and cozy after he could be swaddled anymore. I wasted lots of money. ~Irina

          1. I actually had ordered the polyester one but ended up returning it. I was going to get a cotton one but then I realized that Halo actually doesn’t have cotton at all for the one that I want!
            http://www.halosleep.com/sleepsack-early-walker/

            I am interested in the “Early Walker” line because they have foot holes. My daughter is 19 months and on top of being a walker, she REALLY needs to be able to stretch her legs out fully and move around. She doesn’t like being enclosed.

            Do you know of any similar cotton ones that are somewhat lightweight? I live in California in the Bay Area. It never gets super cold, but cold enough where I feel she needs another light layer.

            Thanks.

  6. Halo states their cotton sacks can only pass flammability standards at the smaller sizes. This is why the larger ones are polyester which is exempt from flammability standards. Search CPSC standard of clothing and textiles under flammable fabrics for additional info. We still don’t really know what is in them but we do know polyester melts and cotton burns.

    Thanks for your post! I am wondering if you know of any organic fleece footies for 3m babies? Thanks so much!
