A popular mid-weight sleeping bag.

The Woolbabe 3-Seasons Organic Cotton + Merino Sleeping Bag is easy to use and extremely versatile. Made from two layers of 30% merino wool and 70% soft organic cotton blend, it's a beautiful fabric exclusive to Woolbabe. Smooth and soft, they're a great option for babies with eczema or sensitive skin.

By varying clothing inside the sleep sack, they're perfect for temperatures from 18 to 28 degrees Celsius, making them ideal for day sleeps year round, and for night sleeps from spring through to autumn. 

The merino component helps to regulate body temperature and keep your baby a comfortable temperature all night

Woolbabe's front zip is quick and easy to use. Simply pop your baby's arms through the arm-holes and zip it closed. The under-arm snaps make it a cosy fit when your baby is near the small end of the size range. A double-ended zip on the front closes at the top and zips downwards, and can also be unzipped from the bottom and opened upwards for nappy changing. The buggy slot in the back of the bag makes it easy to use in the stroller or pram.

Suitable for 3 Months-24 Months.

Available in: Dusk, Midnight, Pebble, and Tide

    Please 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.

    Woolbabe developed and uses innovative fabric as a real point of difference from all the other sleeping bags which are now on the market. They combine two natural fibres - merino wool and organic cotton - to make one luxurious fabric that is used in all their sleeping bags.

    The strength and durability of cotton, with the amazing temperature regulation and moisture absorption of merino is a beautiful combination! The Woolbabe fabric was originally developed by the CSIRO Fabric Division in Geelong, with great attention to details. Their gorgeous fabric designs, along with plush wool filling, have become the signature of Woolbabe.
