Woolbabe 3 Seasons Guide

Super soft, cosy and breathable, woolbabe is loved by parents & babies all over the world. Woolbabe reviews consistently highlight how beautifully soft, gentle and snuggly our signature fabric is and how babe is always super snug when sleeping in their Woolbabe.  And this is reflected in our OhBaby! gold award for best sleeping bag & most recommended product!  Woolbabe has also been picked out as one of the best by editors at the Australian non-toxic awards.


A sleeping bag usually forms a strong sleep association for babies and we highly recommend using a sleeping bag year-round. Sleep sacks are a safer option than loose bedding sleeping bags which can slip up over the face and because it's wearable, your baby will stay comfortable all night, rather than waking up cold after having kicked off their blankets.  

The Sleeping Suit is a good option to move to if your baby starts to climb out the cot or starts to refuse the sleeping bag.  It will keep your active toddler warm and safe.

Woolbabe sleeping bags and suits come in 3 different weights; summer, 3 (all) seasons, winter (duvet weight) and winter weight with sleeves.  The 3 seasons bag is the most versatile option and can be used almost year-round.

How to Layer Your Woolbabe




The Details


Our Woolbabe 3 seasons sleeping bags and suits are perfect for use most of the year and can be used from about 18 to 28 degrees Celsius or 64 - 82 degrees Fahrenheit, by simply varying the sleepwear layers underneath. 

Made from 2 layers of the exclusive woolbabe merino/organic cotton blend, it is extremely versatile and can be worn with just a nappy in the height of summer or 2 or 3 layers in winter.  Made from 100% natural fibres, the Woolbabe sleeping bags are highly breathable and temperature regulating - they help baby stay warm when it's cold and cool when it's hot. Parents "love the convenience of not having to use blankets" and that they "don't have to worry about little one's temperature and comfort".

And in the shoulder seasons when nights can start warm and end cool, you can rest assured that baby is comfortable because the wool component reacts to changes in body temperatures to help baby stay comfy, which encourages everyone to have a good night's sleep. 

Relax! I'm Cosy. This sums up what woolbabe is all about. Helping babies sleep better, staying just the right temperature and helping parents relax about their baby's sleep.

What weight or TOG-rated sleeping bag do I need?


A TOG (Thermal Overall Grade) essentially measures how much a particular fabric insulates and is roughly equivalent to a layer of clothing or a light blanket. Many sleeping bags use the European TOG rating system to indicate how warm the sleeping bag is and what season they are suitable for. The higher the TOG, the warmer the sleeping bag.


All seasons sleeping bags and suits are usually around 1.0 tog, sometimes up to 2.5 tog.  A 1.0 tog bag generally covers room temperatures of 18-24 degrees celsius.  The Woolbabe 3 Seasons Sleeping Bag and suits are a midweight merino/organic cotton blend, equivalent to about a 1.0 tog cotton bag. 


Why are some sleeping bags tog rated and others are not?


Natural fibres, such as Merino are not rated TOG because they adjust according to temperature, and this is why they are so popular.  The Woolbabe Summer Sleeping Bag is equivalent to approximately 0.5 tog.


Sleeping bags with cotton or polyester or that consistently perform to a testing standard or set temperature range tend to be tog rated. Merino is also amazing at wicking moisture away from the skin, meaning sweaty babies won't wake up due to cold, clammy fabric. Woolbabe bags and suits have one of the widest temperature ranges - the 3-seasons bag can be used for rooms 18-28 degrees Celsius (65-82 Fahrenheit), and the duvet weight bag can be used from 14 to 22 degrees (57-71 degrees Fahrenheit).


Why use Merino?


Merino is a highly breathable, 100% natural fibre that regulates your baby's temperature. Wool fibres form a natural air pocket which acts as an insulator, keeping babies warm without sacrificing breathability, so your baby will always be at the right temperature – never too cold, never too hot. Merino can also absorb up to 30% of its own weight in water without feeling damp, helping baby stay comfy on warmer nights.  


Merino is also resistant to mould, mildew and bacteria, maintaining a healthy sleeping environment and preventing odours from developing.


Each Woolbabe comes with a room thermometer


Every Woolbabe sleeping bag or suit comes with a handy room thermometer that indicates the ambient temperature. On the back of the thermometer is a clothing guide, which guides you as to how many layers your baby may need for that temperature and type of bag.


It's good to note that every baby and child is different and it's important not to overheat your baby. The guides below are just that, guides.  Use them as a starting point and adjust accordingly, making sure to check that they are not too hot or too cold.  You can do this by placing your hand on their chest or the back of their neck.  If your baby is red and sweaty, she is too hot, so remove a layer of clothing.


As with bedding we recommend using natural fibre clothing or sleepwear with your Woolbabe, such as merino, which is excellent at wicking away moisture when it's hot and retaining warmth when it's cold, or 100% cotton.

The best guide is to consider whether the heating, bedding and clothing would add up to a comfortable sleeping temperature for you. The ideal room temperature for children is 18 to 20 degrees Celsius, with 18 degrees considered perfect! Please consult your medical professional for further advice if required.
