Temperature & clothing guide for the Sleep Bag range

Please refer to the chart on our temperature guide page.

How do I care for my Merino products

Always follow the care instructions on the packaging. Merino garments should be washed using wool approved liquid only. They can be washed in a machine on the delicate cycle using luke warm water (below 30°C). Merino garments should never be soaked, bleached, washed in hot water, soaps, or spot cleaned. Dry your garments flat in the shade away from direct sunlight. You may iron with a cool setting.

Cocooi Sleep Bag & Go Go Bag

Adjust zip closed before you machine wash on wool cycle, 30°C max.
Only use wool approved washing liquid e.g. Ecover Delicate.

What is a TOG rating?

The British “TOG” value is the international standard measurement of all blankets’ thermal effectiveness (how well it keeps you warm). The TOG rating describes the warmth or ‘Thermal Resistance’ of a fabric, and is widely used in the UK to describe warmth levels of duvets and sleeping bags.

Merino Kids™ products do not have single TOG ratings. The unique temperature control qualities of Merino mean that our products cover a range of TOG ratings. This has been approved by the British Standards Authority.

Merino Wool

Why do you call Merino the ‘wonderfibre’?

Merino is widely known as the wonder fibre, due to its natural abilities to regulate body temperature. It is also a miracle fibre for premature and low birth weight babies. Studies of infants at Cambridge Maternity Hospital, UK, found that those sleeping in Merino settled more quickly, cried less, fed better, and gained weight faster. Merino also naturally prevents the build up of odour, so can be washed less often, and is the perfect fibre for babies with skin allergies and eczema as it won’t irritate even the most sensitive of skin.

My child has sensitive skin/allergies – would Merino irritate this?

Merino is widely known as the wonder fibre, due to its natural abilities to regulate body temperature. It is also a miracle fibre for premature and low birth weight babies. Studies of infants at Cambridge Maternity Hospital, UK, found that those sleeping in Merino settled more quickly, cried less, fed better, and gained weight faster. Merino also naturally prevents the build up of odour, so can be washed less often, and is the perfect fibre for babies with skin allergies and eczema as it won’t irritate even the most sensitive of skin.

Isn’t Merino too hot for warm temperatures?

Merino naturally regulates body temperature. It breathes, and removes any moisture away from your baby’s skin, releasing it into the atmosphere. Synthetic fibres do not have this ability, and trap moisture next to baby’s skin, creating a chill zone. See our temperature guide for more details.

Wool sourcing

Maintaining high animal welfare standards is an essential part of Merino Kids™ values and as a company we believe in best farm practice (non mulesed) and the use of ‘ethical wool’. For this reason we seek to develop relationships with farmers who share our core values.

Merino Kids™ use Merino Wool that is sourced from sheep that have not been mulesed.

New Zealand-grown merino sheep are reared and run on high ground, where fly strike isn’t an issue, so the practice of mulesing is not a problem in New Zealand.

In Australia we source wool from Bally Glunin Park which has received many awards for its approach to animal welfare and land management.

Merino Kids™ is proud to partner with The Woolmark Company and further details of this relationship are available here.

Why use Merino vs other fibres? e.g., synthetics

Modern science still cannot duplicate the amazing natural properties of superfine merino wool fibre. Merino fibre is one-tenth the thickness of a human hair and this extraordinary fineness combined with its natural crimp produce millions of tiny air pockets that trap air to insulate your baby on cooler nights.

The air temperature in a nursery can fluctuate from day to day, and especially into the early hours of the morning. Newborn babies often wake up either too hot or too cold because it takes time for their body to develop the full capability to regulate its temperature. Only merino fibre has the remarkable ability to regulate body temperature to compensate. It captures air to insulate your baby when the room temperature falls, and releases excess body heat and moisture as the room temperature rises, creating the perfect micro-climate around its body.

Merino fabric will readily absorb perspiration and release it into the air to help prevent your baby from overheating and waking up damp. Tests conducted by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia showed that merino fabric has an amazing capacity to absorb liquid - up to 35% of its own weight - compared with synthetic fabrics which are commonly at around 1% absorption. So, synthetic fibres may appear to be warm, but they don’t breathe, making it more likely for your baby to perspire. This creates a moist environment and a chill zone next to your baby’s skin. Bacteria are more likely to survive in these conditions.

Cotton is not as poor as synthetics and typically absorbs moisture up to 24% of its own weight. However, cotton does not release moisture sufficiently and babies sleeping in cotton can still wake up damp and chilled from their perspiration.

The Cocooi™ Range

What is special about the Cocooi Swaddle?

Young lives are precious, and the Merino Kids™ Cocooi™ swaddle helps protect and care for them in a safe, comfortable and natural way:

  • It is the best swaddle for newborn babies up to 3 months.
  • It is soft, fine and smooth on sensitive young skin.
  • Merino wool is naturally breathable making it a very efficient temperature regulator.
  • Ideal for any season.
  • Baby has freedom to move, naturally replicating their time in the womb.
  • Awarded iF Design Awards Seal of Outstanding Design Quality.


Crafted entirely from New Zealand’s finest pure unbleached merino wool, the Cocooi™ Swaddle is luxuriously soft and 100% natural, renewable and biodegradable. It contains no spandex, nor has it been treated with chemicals and it is safe to use for babies with allergies, eczema and sensitive skin.

Merino fibre has a natural elasticity that allows the swaddle to stretch up to one-third of its length before returning to its original size. This natural elasticity, in conjunction with the innovative diagonal-winged design of the Cocooi™ Swaddle explains how it can fit newborn babies up to three months old snugly and securely without resorting to artificial spandex, self-fasteners or constricting arm restraints.

For these reasons and together with merino’s natural temperature-regulating qualities, the Merino Kids™ Cocooi™ Swaddle provides the ideal sleeping environment for a newborn baby in any season. Simply dress your baby in more or fewer layers of natural-fabric sleepwear in cooler or warmer seasons and avoid synthetic sleepwear fabrics such as polyester, because they do not release heat and moisture.


The patented diagonal-winged design of the Cocooi™ Swaddle allows the soft merino fabric to flow naturally in a diagonal direction down over your baby’s shoulders and across the chest. The diagonal wings hug your baby close so they can’t wriggle free and the cross-over swaddle ensures the fabric stays clear of their face while they sleep.

By contrast, traditional swaddling blankets have square corners horizontal to the baby and do not fold naturally across their shoulders and chest. Traditional swaddling blankets must be tugged tightly around your baby’s body causing uncomfortable blanket creases, they can come undone, and there is a risk of blanket fabric gathering up around your baby's face.

Swaddling blankets have advanced in recent years beyond simple square cuts of fabric to specialized ‘swaddlers’ with flaps, pouches and horizontal ‘wings’, but older designs are limited by their square wing shape. To stay in place they often require knots, buttons, snaps or harsh and noisy velcro patches, arm restraints, or multiple layering of fabric.

The award-winning new design of the Cocooi™ Swaddle does not require fasteners or arm restraints, and its graceful diagonal wings are sized for an easy single wrap over your baby’s shoulders and around your baby’s body. This simplifies swaddling, reduces the time handling your baby while swaddling, and makes for a more relaxed sleep-time routine.

Freedom to Move

The Cocooi™ Swaddle ensures your baby has the freedom to sleep and move naturally as they would in the confined space of the womb. They can tuck their hands against their chest, raise up their knees, and kick and punch, without the swaddle coming undone or covering their face. This wouldn’t be possible without the patented diagonal-wing Cocooi™ Swaddle design.

It’s not necessary to immobilize your baby’s arms to prevent startle reflex with the Cocooi™ Swaddle. Your baby can enjoy natural limb movement for comfort and early brain development but won’t scratch, twitch and wake themselves.

The handy leg pouch allows for quick nappy checks and changes in the night without unwrapping your baby’s arms which might wake them. Some swaddles require that you uncover your baby’s feet in hot conditions for ventilation. This is unnecessary with the Cocooi™ Swaddle due to merino’s remarkable ability to release excess heat and moisture and regulate baby temperature.

Car Seat and Buggy Compatible

The Cocooi™ Swaddle’s innovative seat belt vent allows your baby to be swaddled when riding in the car or buggy.

To use the Cocooi™ Swaddle in a child car seat, open it out flat across the car seat and insert the centre strap of the car seat safety harness through the Cocooi™ Swaddle vent. Place your baby in their seat, fasten the safety harness straps around your baby, then wrap the Cocooi™ Swaddle wings around your baby over top of the safety harness straps.

Award-Winning Design

The Merino Kids™ Cocooi™ Swaddle was awarded the Seal of Outstanding Design Quality in the prestigious 2008 International Forum Product Design Awards and it also featured in the 2008 Red Dot Design Awards, which ranks among the largest and most renowned design competitions in the world.

How do I put my baby into the Cocooi Swaddle?

The Cocooi™ Swaddle makes it easy to swaddle your baby quickly, gently and securely in just three easy steps. Simply place baby’s feet inside foot pouch. Wrap short wing down over baby’s left shoulder and left arm, across and under baby. Bring right arm down, wrap long wing down over baby’s right shoulder and around baby twice. Tuck it in and baby will be snug and secure inside the Cocooi™ Swaddle!

How do I transition my baby from being swaddled?

Once your baby starts becoming frustrated with being swaddled (not to be confused with normal arm movement), it is time to wean your baby out of the swaddle and into a baby sleep bag. This will usually happen between 8-12 weeks, We recommend weaning your baby slowly, sleeping your baby with one arm out of the swaddle wrap for 1-2 weeks, then moving to both arms out, with feet still wrapped for a further 1-2 weeks, and finally, moving to a baby sleeping bag, with both arms and legs having the ability to move freely. Some babies will transition at a faster rate, especially if they are a little older.

If your baby is over 3 months, still swaddled and waking in the night, this weaning routine will still work. Past three months your baby will be used to their surroundings and will no longer suffer from startle reflex, so there is no need to create a ‘womb like’ feeling for them.

What is the difference between a Cocooi Newborn Sleep Bag and a Go Go Bag?

The Cocooi™ newborn sleep bag has been designed especially for newborns through to three months of age. We use two layers of 100% superfine merino with a cross over neck line for ease of use. There are no shoulder or arm domes (poppers) and it zips up under the left arm around to the bottom of the bag for easy nappy changing during sleeps. Merino is proven to improve sleep patterns and encourage feeding and sleeping in newborn babies.

The Go Go Bag™ is lined with one layer of 100% superfine merino and has a 100% cotton outer (standard weight) or 100% cotton fleece outer (duvet weight) for added durability, and it is designed to be worn from newborn (7lbs) through to 2 years.

What size is the Cocooi range suitable for?

The Merino Kids Cocooi range has been designed for newborn through to 3 months with a height of 62cm, chest of 44cm and waist of 44cm.

Safe swaddling

Following the media reports about Swaddling on October 29th, Merino Kids™ would like to reassure all customers that its Cocooi™ swaddles are SAFE swaddles. The bottom half of our swaddle is a wide, loose pouch that allows plenty of room for baby to kick and move freely. Most importantly, our swaddle allows the legs to fall naturally in the ‘frog-like’ position and not be hindered by the material. Merino Kids is aware of the concerns of hip displaysia and constantly talks with medical organisations, including the author of the 29/10/13 report, Professor Clarke. As he states in his report: “Commercial products for swaddling should have a loose pouch or sack for the babies’ legs and feet, allowing plenty of hip movement”. Cocooi™ swaddles have been assessed to fulfil these requirements in full.

Cocooi™ swaddles are made from merino wool, 100% natural and non-synthetic. Merino wool ‘breathes’ better than any other material, keeping a baby warm when it’s cold, but also releasing heat and moisture naturally, allowing overheating babies to cool down. This can also reduce the risk of skin allergies.

Safe swaddling is for babies at times of sleep or rest, day or night – but not for 24 hours a day, as babies need playtime to move and develop freely. It’s an age-old practice that promotes healthy sleep patterns – good sleep helps good development. Safe swaddling is from birth until about 3 months old.

If any of our customers would like to visit the showroom for a refresher on how to swaddle safely using our swaddle then please contact us or alternatively view our Cocooi™ Swaddle instruction video on YouTube.

The Go Go Bag™ Range

Why use a sleeping bag?

Baby sleep bags have been used through Europe for generations. Here are the main benefits of using a baby sleep bag:

  1. Baby sleep bags are designed to provide comfort and warmth without the need for additional bedding e.g. top sheets, blankets, duvets.
  2. As there are no sheets or blankets to kick off while your baby is in their baby sleep bag, your baby won’t wake up cold.
  3. As your baby stays a regulated temperature all night, your baby is not likely to wake from the cold (check out our temperature guide for clothing suggestions).
  4. A baby sleep bag promotes safe sleeping as there are no top sheets or blankets to wriggle under with the threat of suffocation.
  5. The baby sleep bag can prevent your baby’s feet from becoming stuck between cot bars.
  6. It aids the transition from bassinet to a cot, and cot to bed, as the baby sleep bag is associated with sleep. This association will also help give your baby a strong cue that it is bedtime and helps set their routine.
  7. You can take your baby sleep bag on holiday, to visit family and friends or simply out to the supermarket and still keep your baby in a safe and familiar environment.
  8. Our baby sleep bags have a patented car-seat vent making it very easy to move from a car-seat or buggy to the bassinet, cot or bed, helping baby with a regular sleeping routine.

Why use a Merino Kids™ Go Go Bag?

The Go Go Bag™ is an International award-winning baby sleep bag which has been designed with the safety and comfort of your baby in mind. It is specifically for babies and toddlers and uses only 100% natural fibres – 100% superfine Merino wool & 100% organic cotton.

It can be taken anywhere, allowing your child to be easily transferred from a car seat or buggy into their cot or bed. It is safe for your child and amazingly practical. A popular alternative to sheets & blankets, the Go Go Bag™ has passed vigorous fire safety tests and is labelled LOW FIRE RISK.

The Go Go Bag™ has many benefits including:

  1. Prevents your baby from waking after wriggling out of their blankets.
  2. Keeps your baby at a safe and comfortable temperature throughout the night.
  3. Merino regulates temperature by removing heat and moisture away from the body and in cool conditions (between four and six in the morning) it insulates.
  4. Babies associate the bag with sleep so will settle more easily in unfamiliar surroundings.
  5. Safely used by children with allergies, eczema and sensitive skin.

  4. For Winter use only. Adjust clothing layers accordingly.

We also have 100% Organic Cotton bags that are ideal for use in the hot summer months and suitable for bedroom temperatures of 24°C-27°C.

Do I need more than one Go Go Bag?

We strongly recommend the rotation of two sleeping bags as over a six-month period most children sleep on average 3,000 hours and rotating two bags enables you to get the most out of your Go Go Bag. Your Go Go Bag is made from all natural fibres and contains no polyesters so please follow the washing instructions carefully.

How big is a Go Go Bag?

Your baby can go into a Go Go Bag from newborn up until 4 years of age. For the first three months, you may wish to use the dome adjustment system under the arms. When using a Go Go Bag we advise a minimum weight of 3.2kgs/7lbs.

The Merino Kids Go Go Bag comes in two sizes:

  1. Baby (0-2yrs)
    Length 86cm; Chest Width 28cm; Neck Opening 12cm; 1/2 Arm Opening 17cm
  2. Toddler (2-4yrs)
    Length 104cm; Chest Width 32cm; Neck Opening 14cm; 1/2 Arm Opening 20cm

For an approximate guide visit our sizing page.

How do I put on my Go Go Bag?

Simply unzip the bag, undo the shoulder domes, and lay baby on top of bag. Insert arm through armhole, and dome up the second shoulder. Zip bag up, and ensure that baby is sitting comfortably inside the bag before laying baby to sleep.

What other bedding do I use with my Go Go Bag?

Use only a flat or fitted bottom sheet on the bassinet/cot/bed and place your baby in the Go Go Bag. This will prevent them waking up, getting out or tangled up in bedding. It is not necessary to use blankets, top sheets or duvets when using the Go Go Bag.

Go Go Bags don’t have sleeves – won’t my child get cold?

This is to ensure air circulation, Babies sleeping under traditional blankets rarely sleep with their arms inside the covers. We recommend layering garments to ensure your child is perfectly adapted to their environment. The best way to measure your babies temperature is to check behind their neck. So long as their core temperature is okay, arms and hands can be cooler due to poor circulation in the first 12 months.

I want to put my infant into a toddler (2-4 year) bag – how big should they be for this?

We base our sizing on the 50th percentile of babies according to New Zealand Plunket guidelines. If your baby is getting too big for the Baby Go Go Bag, they may need to start sleeping in the toddler bag. The neckline and armholes are bigger in the toddler bag, so this will need to be taken into consideration when deciding which bag to use.

Our Toddler Go Go Bags have domes (poppers) under the arms so that you can fasten them securely if moving them into this size before 2 years of age.
