What is the difference between sleeping bag weights

There’s no better feeling than watching our little sleepers wrapped up and soundly snoozing.

For a while now, sleeping bags have become the answer for many parents looking for the perfect sleep solution. Sleeping bags offer the flexibility to modify a baby’s sleeping environment by using different textile weights.

At Merino Kids, our Go Go Sleeping Bags are available in three weights, Standard, Duvet and Winter which are individually crafted to ensure the perfect sleeping temperature. However, if you’re new to the world of baby sleeping bags, we’ve listed all you need to know including what our weights mean, the differences they offer and why using sleeping bags are super important in aiding your little one’s quality of sleep.


Sleep is an essential part of your baby’s routine (they won’t do much else in the first few months) so making sure they are safe and comfortable will offer you and your little one important rest periods. More specifically, your little one’s sleep temperature plays an enormous factor in assuring they rest well.

Many experts recommend an optimum room temperature of 16-20֯C, including the World Health Organisation (WHO) but for little ones under 12 months, maintaining their optimum temperatures can be more sensitive.


When searching for the perfect baby sleeping bag weight, it’s important to note that depending on need, the thicker weight of the bag will be the outer, as the lining of all our baby sleeping bags is 100% superfine merino.

Picking the right weight for your little one will also depend on the climate you live in and the time of year you’re shopping for. It’s handy to have a few different sleeping bags to hand in varying sizes so you can cycle them throughout the year, along with spares to account for any night-time accidents. The beauty of merino wool sleeping bags is that it boasts naturally temperature-regulating properties, so it’s even more versatile to use throughout varying climates.
