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

The wait is over. Our long sleeve Merino Baby Romper is finally here. It 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)

It is made out of our signature quilted fabric with merino wool batting and soft double knit cotton covers.  The fabric is scientifically proven to be a great sleeping wear choice for babies, including eczema babies.

KO-COON Long sleeve Merino Baby Romper is designed to fit from 3 to 6 months old.


  • 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 romper will help to lower down the excess heat and if the baby is losing body heat, the 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 romper is designed with soft cotton hidden mittens and hidden booties, to help preventing loosing body heat. 

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

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 garments 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. 

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.
