Woolino Merino Wool Baby Sleep Sacks – The Best All-Season Sleep Solution
At Woolino, we believe better sleep begins with better fabrics. Our Ultimate Baby Sleep Sacks are expertly crafted from the finest Australian merino wool, lined with soft organic cotton to create a naturally breathable, temperature-regulating sleep environment for your baby.
Unlike sleep sacks with fixed TOG ratings, Woolino’s all-season baby sleeping bags work in harmony with your child’s body. Merino wool naturally regulates temperature, keeping your baby warm in cooler months and comfortably cool in warmer weather while wicking moisture away to help prevent overheating. The result is a safer, more restful night’s sleep in every season.
Our innovative universal-size design fits babies 2 months to 2 years old (or toddlers 2 - 4 years), offering exceptional value. This extended-use approach eliminates the need to size up or switch weights as your baby grows,

FAQs
What is a baby sleep sack?
A baby sleep sack is a sleeping bag designed for infants. It is made of softer materials – merino wool in the case of Woolino sleep sacks – and is designed to fit snugly around the baby’s body. Baby sleep sacks are the ideal solution for safe and comfortable sleep. They regulate the temperature and keep the baby cozy.
When can my baby start using this sleep bag?
The best time to start using the Woolino sleep bag is between two months and two years of age. The ideal period to start using the bag would be when the baby overgrows the swaddle. At that point, a sleep bag will be the preferred option. You can adjust Woolino sleep bags to fit your baby precisely using the handy snaps under the arms.
What should my baby wear when sleeping in a Sleep Bag?
Ideally, your baby should have sleepwear made of similar materials to the Woolino sleep bag. These may be clothes from merino wool or cotton. The precise choice of clothes will also depend on the temperature. You can see a handy chart on this page, explaining the recommendations.
Are sleep sacks safe for babies who can walk?
Sleep sacks are completely safe for babies, even when they can walk. Woolino has a line of walking sleep sacks with leg space. If you follow the age guidelines, there’s no reason not to get a sleep sack for your little walker.
Do you put baby in sleep sack for naps?
Since sleep sacks ensure the highest comfort and optimal sleeping positions, getting a sleep sack on for a nap isn’t a bad idea. Of course, a sleep sack isn’t necessary for short naps. However, it certainly won’t hurt. If you have the means to make your baby’s sleep as comfortable as possible, why not use it?
