Not all Stretchy wraps are created equal

By Rachel Coy – North East Sling Library

First the basics – What is a wrap? A wrap is a continuous piece of fabric which when tied in a variety of positions allows you to carry your baby. There are two main types of wrap: stretchy and woven. I am going to focus on explaining stretchy wraps, as often this is a person’s first introduction to a using sling.  Stretchy wraps are suitable from birth and can be used with premature babies during Kangaroo Mother Care. But it is important to remember that although we tend to group this type of wrap together, that not all stretchy wraps are equal.  Each brand of stretchy wrap has different qualities, such as the size of the wrap, the stretch, elasticity, size of tapers and even the thread used. This makes finding the right stretchy often as difficult as finding the right woven wrap or other type of sling. I aim to be able to explain the differences and enable parents to find the right stretchy wrap for them.

Stretchy wraps are extremely popular as an introduction to wrapping. Manufacturers such as Moby, Kari-Me and hybrid carrier ‘Caboo’ by Close Parent are often the most easily accessible in mainstream shops and websites. The basic skills of learning to wrap with a stretchy wrap can easily be transferred across if parents decide to progress to a woven wrap.  Not all stretchy wraps are the same and this includes each manufacturer choosing to have their own name for the same type of carry. This can be highly confusing for a first time user. The main carry advocated by manufacturers is the Pocket Wrap Cross Carry.  This carry can be pre-tied and remained tied after baby has been removed, allowing you to place baby back in the sling again without having to re-tie. This carry is also known as the ‘Hug Hold’ in Moby Wrap instructions, ‘Tummy to Tummy’ in Moby and ‘Love your baby hold’ in the Boba Wrap (formerly Sleepy Wrap). Yet it is the same carry. This carry allows parents to hold their children upright (which can be done from birth) with their legs either in or out.  Instructions on how to tie this type of carry can be found HERE.  Stretchy wraps can also be used for carrying older babies on the caregiver’s hip.

Now we need to talk safety. As with any sling it is crucial to remember the TICKS guidance. Carrying your baby in a sling is a very enjoyable experience and has many benefits for both the baby and caregiver but it is crucial that it is done safely.  Some manufacturer’s instructions include instructions for how to do cradle carries, forward facing out or back carries.  I would not recommend the use of the cradle position or, if using a traditional stretchy wrap, a back carry.  With cradle carries it becomes more difficult to keep babies spine supported and their chin off their neck. The nature of a stretchy wrap means that it will stretch and unfortunately this can mean that a baby on the wearers back leans backwards and falls out. Most manufacturers have now removed this carry from their instructions and as a rule I would advise no one to undertake a back carry with a stretchy wrap, with the exception of a stretchy hybrid such as the  Je Porte Mama Bebe (JPMBB) or Wrapsody Bali Breeze Stretch.


Traditionally stretchy wraps are 100% cotton but the JPMBE for example is 95% cotton and 5% spandex.  The table below compares sizes of wraps, linen mixes, weight etc. to allow parents to compare different slings in one place. It is not just the mix of thread used to create the fabric but also the weave of the fabric which is important.  When considering different types of stretchy wraps we should remember that how much a wrap stretches is different to how much elasticity it has. The stretch of a wrap is the pull from A to B, and the elasticity is the pull back (A to B to A). It is the elasticity of a wrap which offers the wearer and baby the support.  The more elasticity the more supportive the wrap will be and the longer it will last.

Approximate weights g/m as difficult to calculate with the tapers but gives you an idea. Discussion of stretch = pull from A to B. Elasticity is the spring back so A to B to A again.


Boba/Sleepy Wrap – 530cm long x 50cm wide. Made from 95% Cotton and 5% Spandex. Quite long tapers. Very stretchy but elasticity isn’t great. Good for smaller babies but not toddlers. Has 2 way stretch along length and width. Not too bulky. Fits into small storage bag for transportation. Approx weight g/m = 92g/m

Cot 2 Tot – 470cm long x 50cm wide. Made from 95% Cotton and 5% Spandex. Quite long tapers. Very stretchy, not much elasticity. Similar to the Boba wrap. Folds small for storage/transportation. Approx weight = 110g/m

Calin Bleu Microfleece – 535cm long x 50cm wide. Made from 100% polyester microfleece. Very soft. Quite supportive. Doesn’t stretch too much = 101g/m

Ellevill – 400cm x 70cm short and wide (width similar to JPMBB). Made from 100% cotton so not overly stretchy. Tapers aren’t too long. Possibly not the best sling for fluffier mamas. 100% cotton so doesn’t stretch too much and feels more like a stretchy hybrid than a woven. I have spoken with Ellevill and they have said that these are currently a sample length and others will be longer. I am only a size 10 and can just about do a pwcc but not easily. In my opinion good elasticity. Approx weight = 190g/m

Moby – 550cm x 62cm. Stretchy but not that elastic. Stretchies only along width of wrap. Quite thick.  Approx weight 136g/m

JPMBB – 500 x 70cm. 95% cotton, 5% spandex. A stretchy hybid with excellent elasticity so supportive even with older babies and toddlers. Similar to the Wrapsody Bali Stretch. Not too stretchy but very elastic which gives the support. Approx weight 180g/m

Hoppediz Maxi – 540cm x 55cm – 100% cotton. Not brilliantly supportive as very stretchy and doesn’t have that much elasticity to it. Good for smaller babies and premature babies as not too wide. Approx 119g/m

The direction of the stretch, whether width ways from top to bottom rail or length ways from end to end also effects how supportive a wrap is.   Most wraps stretch because of the way they are woven not because of the fibres they are made from.  The rib knit of most stretchy wraps means they cannot stretch vertically, horizontally and diagonally. The more ways a wrap can stretch the more supportive it will be.  For example the JMPBB wrap stretches in every direction. The density of the fabric also means that it can be used comfortably to carry older children, where as those which are not as dense do not offer the same levels of support.  Stretchy wraps which only stretch in one direction are harder to carry older children in and this can result in the fabric sagging as the child gets heavier.  When a wrap has started to sag it can often be revived by washing it. The ‘just washed’ factor helps to tighten the fibres up and make the sling more supportive but this is a temporary fix.

In summary, when considering what stretchy wrap to buy consider the following:

  • The stretch
  • The elasticity
  • The density of the fabric
  • The weight (grams per metre)

    Fab read Rachel. It’s great to have a lot of information in an easily digestible format. There are so many baby carriers out there and I feel lost at times as to what to try. I have mei tais on order for my twins so here comes the baby wearing. I can’t wait. Next, to learn how to tandem carry.

    Great idea for a post. I am not sure that I agree with everything – for instance, sometimes the more stretch the more the carrier sags as the weight of the child increases, and it then becomes more important to tie the carrier tighter. This require experience. Your point on elasticity is interesting, but I am not sure that it would hold-up to heavier babes. The carriers I make are a single knit fabric with stretch in only one direction. I still carry my 20 lb toddler in it without any sagging or discomfort. We don’t do back carries – but the hip works if we need it. I think that the reason JPMBB can be used for back carries isn’t because it has multi-directional stretch, but because it’s width is much greater than the average stretchy. Regardless of my opinions about stretch and elasticity, however, I really love the points you offer on safety and that “not all stretchies are made the same”. Thanks.

    Thanks for the info, does anyone know what the best wrap for twins are. I have had a look around and was hoping to use our close carrier for both but don’t think we will be able to. I have looked at the Moby and it looks pretty good so may give that a go unless someone has any other suggestions.
