Explanation TOG values


Heat and TOG values of sleeping bags generally

Below you will find a guideline for the use of the correct TOG values. However, this is an advice. The right choice also depends on the ambient temperature and the body heat of your baby.

You can roughly maintain the following. A sleeping bag of 3.5 TOG is very warm (say Eskimo material) a sleeping bag of 0.2 TOG is very thin (suitable for warm nights in the summer). In addition, you can of course also vary with the layers of clothing. Only a bodysuit or if it is colder a pajama is added. This means that 2 sleeping cases with 2 different TOG values are sufficient. Go by your feelings and check if your baby is too hot or too cold and adjust the layers & possibly sleeping bag accordingly.

Specifically: a sleeping bag with a TOG of 2.3 / 2.5 is ideal for a bedroom with a temperature between 16 and 20 °. So if your room is warmer, you go to a sleeping bag with a lower TOG value (1). If your room is cooler, go to a sleeping bag with a higher TOG value.
  Season   Temperature room TOG value advice  
  Summer   20 - 24 degrees 1.0 or lower  
  Spring / fall   18 - 21 degrees 1.3, 1.7  
  Winter   16 - 20 degrees or colder 2.3, 2.5 or higher  

In addition, each sleeping bag states which season it is suitable for. That way you can make your choice even easier.

Useful facts about the Tog value:
  • The TOG (Thermal Overall Grade) with which the VBKV works in the Netherlands runs from 0 to 4.
  • The higher the TOG value, the warmer the product.
  • The TOG value applies at room temperature, therefore not outside.
  • Tucking babies too hot can be risky. So always choose the correct Tog value.

TOG values Lodger

The ideal TOG value

First of all, it is important to ensure a constant room temperature that is between 16 and 20 ° C. In this graph you can see at which temperature you can use which TOG value at most !

The guideline is as follows: at an average room temperature of 16-20 ° C, a TOG value of 2.5 to max 3.0 TOG must be maintained. By making a simple sum based on the table above, you can check whether your child is dressed too warm or too cold.

At Lodger we have our materials tested for their TOG values. The Hopper Sleeveless has a TOG value of 0.5. This means that it can be used well at a room temperature between 21 and 24 degrees Celsius. The Lodger sleeping bag has a TOG value of 2.5. This means that it can be used well at a room temperature between 13 and 18 degrees Celsius.

You can increase the TOG value by putting your child on a long-sleeved bodysuit or pajamas under the Hopper or by using a blanket such as the Dreamer from Lodger.

Note: It is important to keep checking comfort on the neck and feet. The skin must not feel damp or cold. The above values are based on babies who can keep themselves warm. Every child is different so pay close attention to the heat regulation of your child. In addition, always ensure that the bed is made in accordance with the guidelines for safe sleep. Always check in the neck of your child whether it feels too cold or too warm, the table above remains a guideline.
