TOG or temperature for a baby sleeping bag? How to read the warmth rating

Short answer: Some baby sleeping bags are labeled with a TOG value, while others - including Lilla Villa sleeping bags - are labeled with a recommended temperature range. With Lilla Villa, you should therefore choose based on the temperature range of the specific sleeping bag, the room temperature, and the product instructions rather than trying to convert it to TOG.

What is the difference between TOG and the temperature rating of a sleeping bag?

TOG measures a textile's insulating ability. A temperature range instead indicates the temperature conditions the specific sleeping bag is designed for according to the product instructions.

In other words, the two types of information describe warmth in different ways. You should not automatically convert a temperature range into a specific TOG value, because materials, construction, and the manufacturer's testing or instructions may vary.

Do Lilla Villa sleeping bags use TOG?

Lilla Villa sleeping bags are selected according to their recommended temperature range. On the specific product page, you can therefore see which temperature range the model is designed for.

If you need to choose between our different temperature ranges, you can go directly to Which sleeping bag temperature should you choose for your child?. Here, we cover models for 0–15 °C, 10–20 °C, 15–22 °C, 20–25 °C, and 25–35 °C, among others.

Should I convert the temperature range to TOG?

No. If the sleeping bag already includes temperature guidance, it is more relevant to follow the specific instructions than to try to find an equivalent TOG value online.

General TOG charts from other brands may be based on different materials and constructions and should therefore not be used as product guidance for a Lilla Villa sleeping bag.

How do I choose the right Lilla Villa sleeping bag?

1. Check the temperature in the room where your child will sleep.
2. Check the temperature range of the specific sleeping bag.
3. Follow the product instructions regarding use, size, and clothing.
4. Check your child on the chest, back, or neck. Warm or damp skin may be a sign that your child is too hot.

Why is room temperature more important than the season?

The temperature outside does not necessarily tell you how warm it is in your child's bedroom. A heated room in winter can be warmer than a cool room on a summer night. Therefore, your choice should be based on the actual room temperature and the temperature guidance for the specific sleeping bag.

Frequently asked questions

What does TOG mean?

TOG measures the insulating ability of textiles. A higher TOG value generally means more insulation.

What TOG rating do Lilla Villa sleeping bags have?

Our sleeping bags are selected according to their stated temperature range. If a specific model is not labeled with a TOG value, you should not assign it a TOG value based on a general chart.

Is 10–20 °C the same as a specific TOG value?

Not necessarily. A temperature range and TOG are not types of information that should be converted directly without documentation for the specific model.

Where can I find the right temperature?

See the product page for the specific sleeping bag and our guide to choosing a sleeping bag based on temperature.
