About KO-COON Merino Baby Romper - play &/or sleep

Our Merino Baby Romper  is genuinely a superhero when it comes to baby's sleep and play, especially in cooler weather, thanks to the unique super powers of merino wool. It improves the quality of sleep and general being by creating a micro climate around baby's body by regulating the body temperature and wicking away moisture. 

The romper is perfect for playing and napping and overnight sleeping (soft cotton top and bottom layer)

Made out of double layer of cotton with merino wool in between, our quilted signature fabric is so soft to touch. Fine merino wool is scientifically proven the best sleeping wear choice for babies, including eczema babies.

KO-COON Merino Baby Romper is designed to fit from 6/7 Months right up to 24 Months +. Even earlier for bigger babies.


  • Luxuriously fine quilted cotton & merino wool fabric which creates a micro climate around the baby’s body by regulating the body temperature and wicking away moisture. If the baby overheats, the sleeping bag will lower down the excess heat and if the baby is losing body heat, the merino romper will keep him warm.
  • The fabric is naturally antibacterial and dust mites free.
  • A long zip to make it easy if you want to change nappies or potty train
  • The zipper features a pull guard in order to protect child skin
  • The feet feature promotes child independence and avoid tears of frustration for being trapped in a sleeping bag
  • The feet can be tucked away when the baby is very little or goes to sleep

All babies are growing at different pace so an age recommendation needs to be correlated to the garment size and baby’s measurements. Our Romper measurements are:

  1. Shoulder to ankle : 87cm
  2. Shoulder to inside leg: 60cm
  3. Under arms side to side: 37cm

Let’s talk about TOG

The TOG rating describes the warmth or "Thermal Resistance" of a product and is widely used to explain warmth levels of duvets.  Unlike duvets, infant sleeping bags have lower tog rating numbers. The TOG indicates approximately how many blankets the sleeping bag is equivalent to. Bags with rating of 0.5 and 1 or below are for spring/summer use. Bags with rating 2-2.5 are for autumn/winter. 

Sleeping bags with polyester or man-made fiber fillings have to go through a standard testing to be TOG rated, especially to avoid the rick of overheating.

Merino wool has it all! The sleeping bags made with Merino wool are not TOG rated, as these natural fibers adjust the warmth according to temperature. This is one of the reasons why natural fiber Merino wear is so strongly recommended. The merino wool is highly breathable, naturally regulates baby’s body temperature, keeping baby warm in winter and cool in summer. As a result, traditional TOG tests (which are designed to test synthetic fabrics) are not an accurate indicator of the warmth of merino products. 

Even if our Merino Baby Romper seems lightweight, it is warmer than a thicker sleep bag

This is a common concern if you don’t know much about merino wool. Merino wool is lighter than traditional wool as well as a lot of synthetic materials on the market. 

The nature and the sheep tested merino wool at extreme temperatures. The merino breathes and wicks away moisture (sweat) in summer, yet insulates in winter. Gives one the greatest warmth for weight, while being extremely light and soft.

The air is trapped between fibers and creates a body of warm insulating air. Merino wool fibers naturally wicks away moisture. While heavier and bulkier synthetic fibers can seem 'warmer', they actually trap body moisture against the skin, causing your baby to sweat and overheat, to develop rush and eczema.

Our Merino Rompers are recommended to be used in room temperatures up to 21 degrees.

Simply adjust the layers of clothing worn underneath  to suit the nursery or home temperature. We recommend to be used in conjunction with other natural fibers garments (i.e made out of cotton or hemp). We recommend you also regularly check your little one behind the neck or on the stomach to ensure they are not too warm or too hot.

How to care about KO-COON Merino Baby Romper

We recommend gentle wool cycle machine wash with wool detergent.
