The Merino Kids Baby Sleep Bag is the ultimate stylish and functional baby sleep sack for discerning parents and it was awarded the Seal of Outstanding Design Quality in the prestigious 2007 International Forum Product Design Awards. Its award-winning design, remarkable natural merino fabric and quality workmanship set it apart.
Your baby has the freedom to move naturally in their Merino Kids sleep sack, but unlike with sheets and blankets, they cannot get entangled or wriggle out and they do not wake uncovered and cold. This means your baby sleeps better as they stay cozy and warm all night without overheating.
The Merino Kids baby sleep sack fits babies up to two years old and you won't need to buy larger sizes every few months as your baby grows. The contoured knitted bodice fits snugly around your baby's chest and neckline ensuring the fabric stays clear of their face, and as an extra precaution press studs under the arms prevent newborn babies slipping down.
The Merino Kids toddler-size sleep sacks fit infants from two to four years old.
The Merino Kids sleep sack is 100% natural, renewable and biodegradeable. Each baby sleep sack is crafted from New Zealand's finest pure unbleached merino wool and its outer layer is all-natural fine cotton for extended durability to withstand active toddler wear and tear.
Many generations of evolution have endowed the merino sheep from New Zealand with an amazing superfine wool fiber that modern science still cannot duplicate. The extraordinary fineness of merino fiber and its natural crimp produce a luxuriously soft fabric laced with millions of tiny air pockets that trap air to insulate your baby on the cooler nights. Merino fiber breathes exceptionally well, absorbing and releasing moisture to cool or warm your baby's body as their room temperature rises and falls throughout the night.
Regulates Body Temperature
The air temperature in a nursery will often fluctuate as heating or air conditioning switches on and off. Babies can take as long as a year to develop the full capability to regulate their own body temperature and just a few degrees of variation in room temperature can cause them to wake up cold or overheated. Merino fabric has the remarkable ability to regulate a baby's body temperature to compensate. It captures and circulates air to insulate your baby when the room temperature falls, and releases excess body heat and moisture as the room temperature rises, to create the perfect micro-climate around their 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 around 1% absorption. For this reason, babies sleeping in merino are much less likely to overheat than babies in synthetic sleep sacks or blankets.
Cotton is not so poor as synthetics at absorbing moisture and CSIRO testing has shown that cotton fabric typically absorbs moisture up to 24% of its own weight. However cotton does not release moisture sufficiently and babies sleeping in cotton sleep sacks can wake up damp and chilled from their perspiration.
The temperature-regulating capability of the Merino Kids baby sleep sack makes it the ideal all-year-round baby sleep sack, perfect for nursery room temperatures from 65°F to 75°F (18°C to 24°C). Simply dress your baby in more or fewer layers of natural-fabric sleepwear in cooler or warmer seasons. Try to avoid synthetic sleepwear fabrics such as those containing polyester because they do not release heat and moisture.
For cooler rooms, we recommend the winter-weight Merino Kids baby sleep sacks which have an additional layer of natural-fiber insulation and will keep your baby snug in room temperatures from 59°F to 68°F (15°C to 20°C). Merino Kids winter-weight sleep sacks are available in two sizes: for babies up to two years and for toddlers two to four years.
Merino Kids sleep sacks can be used safely in a broader range of temperatures than non-merino sleep sacks because of merino's remarkable natural temperature-regulating properties. Use a standard Merino Kids sleep sack when you might otherwise use non-merino sleep sacks of TOG ratings 1.0 or 2.0. Use a winter-weight Merino Kids baby sleep sack when you might otherwise use non-merino baby sleep sacks of TOG ratings 2.0 or 2.5.
Merino Kids use premium quality superfine merino fiber, one-tenth the thickness of a human hair, which produces lightweight cuddly soft merino fabric, perfect against your baby's sensitive skin.
Made entirely of natural fiber, and fastened with nickel-free press studs, the Merino Kids sleep sack is safe to use for babies with allergies, eczema and sensitive skin. Merino fiber is naturally fire resistant and you can rest assured the Merino Kids baby sleep sack has not been treated with fire retardant chemicals that can irritate sensitive skin.
Car Seat and Stroller-Compatible
The Merino Kids baby sleep sack can be used not only at home but also for venturing outside the house, whether it be a short stroller walk, a car ride to the supermarket, or air travel. The innovative safety belt aperture allows your baby to wear their sleep sack safely in a child car seat or stroller, making it easy for you to transfer them asleep to and from their crib. You won't need to pack blankets and layers of clothing for the trip, and your baby will associate their sleep sack with bedtime so will settle more easily in unfamiliar surroundings.
The durable Merino Kids baby sleep sack can be machine washed and tumble-dried on a low heat setting. Wash after wash it will keep its shape and color. Since merino is naturally resistant to stains and odors, the Merino Kids baby sleep sack does not require frequent washing if aired regularly. Synthetic fibers in contrast are oil-based and wearing and washing of synthetic baby sleep sacks can lead to 'greying' caused by the build up of oil contaminants in the synthetic fibers. You will not experience this problem with 100% natural merino. Please see washing instructions below.
Naturally Fire Resistant
Merino fabric is naturally fire resistant and the Merino Kids baby sleep sack is rated low fire risk. When exposed to flame, it does not melt and stick to skin like synthetic fabrics.
Stylish Striped Designs
Your baby will look their very best in stylish striped designs which include Cornflower blue, Oatmeal, Dove Grey, and French Navy for baby and toddler sleep sacks, plus Wild Poppy and Sandshell for the winter-weight sleep sacks. Check out also the special Limited Edition designs which are available from time to time.

How To Wear
The Merino Kids baby sleep sack is worn over pajamas or a 'onesie' and takes the place of top sheets, blankets and comforters. It ensures your baby is always sufficiently covered and removes the risk of bedding covering their face. When dressing your baby in their Merino Kids baby sleep sack, the Merino Kids label goes to the baby's back.
Secured by a full-length zipper down one side and nickel-free press studs at the shoulder, the Merino Kids baby sleep sack conveniently opens up flat for easy dressing and zips from the bottom-up for quick diaper checks and changes in the night. The high quality self-locking zipper is carefully sewn inside the baby sleep sack lining so it won't scratch your baby's delicate skin. There are no harsh and noisy velcro patches.
Merino Kids baby sleep sacks are designed with baby safety in mind:
- Sleeveless to allow for free circulation of air to help prevent overheating. Babies sleeping under blankets rarely sleep with their arms covered and your baby will be comfortably warm in the Merino Kids sleeveless design.
- The baby sleep sack fabric stays clear of your baby's face. The premium quality fabric is knitted, not woven, allowing the baby sleep sack to fit snugly around your baby's chest and 'move with your baby'. It won't bunch and restrict your baby's movement, nor ride up and interfere with their breathing. As an extra precaution, the Merino Kids baby sleep sack has special press stud fasteners to prevent smaller babies from slipping down.
Remember always to place your baby on their back to sleep.
For babies under 17lb (8kg):
- Reduce the size of the baby sleep sack arm holes by fastening the additional press studs under your baby's arms.
- Fold up the lower end of the baby sleep sack across your baby's chest and tuck it firmly under your baby's arms.
For use in a carseat or stroller:
- Place your baby in their baby sleep sack in the child car seat or stroller.
- Thread the car seat or stroller harness crotch strap through the baby sleep sack apertures between their legs.
- Connect the shoulder and crotch straps of the car seat or stroller harness over the top of the baby sleep sack.
How To Wash
The Merino Kids baby sleep sack is made from only natural fibers. Please follow washing instructions carefully.
- Use only wool-approved washing detergent. Do not soak.
- Machine Wash: Close the zipper before you wash on a gentle wool cycle, 100°F (40°C) maximum water temperature.
- Hand Wash: Use lukewarm water to massage the baby sleep sack gently. Rinse thoroughly. Remove excess water by rolling it in a towel. Do not wring.
- Drying: Dry flat away from direct sunlight, or tumble dry on a low heat setting.
- Can be drycleaned.
- Many mothers recommend having two baby sleep sacks to allow for night-time 'accidents' when one sleep sack might need to be washed.
