Duvet Weight with Sleeves Guide

Filled with 100% merino wadding, the Woolbabe Duvet Sleeping Suits and Bags with Sleeves are our warmest styles. They feature a merino & organic cotton blend outer and 100% organic cotton lining.  The arm sleeves are are quilted with a slightly lighter weight of merino than the main bag.


Award-winning Woolbabe is loved by parents and babies. The signature Woolbabe fabric is super soft, breathable and made from 100% natural fibres.  There's nothing better for baby's delicate skin.  And with 100% merino filling, parents know baby will be cosy & snug all night, without overheating.


Sleep sacks are a great option for babies and can be used from birth. They are a safer option than traditional bedding, which can become tangled or slip up above the face.  And because it's a wearable blanket, parents can rest assured that baby will be cosy and comfy all night, not waking cold after having kicked off their blankets. 


For older babies and toddlers, the Sleeping Suit is the perfect option.  It allows a little more movement and independence whilst still ensuring your little one is warm all night.  Woolbabe sleeping bags and suits come in 3 different weights; summer, 3 (all) seasons, winter (duvet weight) and winter weight with sleeves.

The Details


The Woolbabe Duvet Weight Sleeping Bags and Suits with Sleeves are our warmest styles and are designed to be used in winter, for room temperatures of 14-22 degrees Celsius or 57-72 degrees Fahrenheit by varying the clothing underneath. 

Filled with 100% merino wadding, the Duvet Weight Bags & Suits with Sleeves are super cosy, yet breathable, creating a warm pocket of air around your little one. The Duvet Woolbabe is a quilted style, so feels more like a quilt or layers of wool blankets.  It is lined with a smooth 100% organic cotton which makes it ideal for babies with sensitive skin.  The outer is made from Woolbabe's signature 30% merino / 70% organic cotton blend, so it's buttery soft to the touch.  The sleeves are made from quilted fabric, but are a slightly lighter weight than the quilting of the main bag. The sleeves also have a cuff to extend the longevity of the bag or suit. Roll the cuff up when bubs is little, and then let it down as your little one grows.

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.  The Duvet Weight Sleeping Bag with Sleeves is approximately equivalent to a 3.5 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 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 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 sleeping 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.

Note: This is a guide only. It is important not to overheat your baby. 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 16 to 20 degrees Celsius, with 18 degrees considered perfect! Please consult your medical professional for further advice if required.
