Types of Sleeping Bags

What are the different types of baby sleeping bags?

It can feel like there are so many different types and designs of sleeping bags, making it hard to know which one is right for your little one. Sleeping bags tend to be grouped by their TOG rating, so whilst it can feel like there alot of different options, the most common categories are for seasonal changes from summer to winter.

It is good to know the difference between each TOG rating and types of sleeping bag so you can make an informed decision on which style is best for you and your little one.

Let’s take a closer look.


As the temperature and seasons change, so should your little one's sleepwear. Summer sleeping bags have a lower tog rating and are thinner to help breathability and keep your little one cooler on hot summer nights.


As the darker nights draw in and the weather turns colder your little one will need a warmer and thicker sleeping bag to keep them cosy at night. Winter sleeping bags have higher TOG ratings ideal for cooler room temperatures.

All Season

There are also sleeping bags that are designed to be used all year round and don't tend to have TOG ratings. They are commonly made from Merino wool. The magic of Merino is it's amazing ability of being able to release moisture and regulate your little one's temperature to keep them at the perfect temperature in all seasons. These eliminate the need of having multiple seasonal sleeping bags, making them a popular choice.

Swaddle Bags

This style is more associated with newborns. These follow the same principle of a wearable blanket, but offer a more snug fit and closed arm holes. The design will help baby feel snug and securely swaddled without the need for complicated wrapping. Some have a 2 in 1 design, converting from a baby swaddle bag to a baby sleeping bag with poppers in the armholes.

Baby Sleeping Bag TOG Chart

Finding the right sleeping bag for your little one is mostly determined by the ambient temperature of their sleeping environment. Most sleeping bags will have a TOG rating which determines how heavy or thick the fabric is. Unlike adults, little ones can't regulate their own temperatures just yet so it's important to pick a sleeping bag based on the temperature of their room to get the right TOG rating.

Once you know the ambient temperature, match to the TOG chart here to find the perfect sleeping bag for your little one. As a general rule, the warmer the room, the lower the TOG should be.

We have also put some handy information on what your little one should wear underneath their sleeping bag depending on the temperature of the room and TOG rating.
