When researching the first Sleeping Bag for your child, you come across the so-called "TOG rating." But what does the TOG rating actually mean?

TOG is a unit of measurement that represents the thermal resistance of textiles: 1 TOG is equal to 0.1 m² K/W. The higher the thermal resistance or TOG rating, the warmer the Sleeping Bag. The right TOG rating depends on the room temperature where your baby sleeps. The ideal room temperature is between 16–18 °C.

The TOG rating for the optimal sleep temperature

Manufacturers use the TOG system to help parents choose the right baby sleeping bag for the room temperature. However, these are only recommendations for parents. The following always applies to TOG ratings for Sleeping Bags:

  • The thickness of the sleeping bag and the baby's Clothing Line should be adjusted to the room temperature , not the season.

  • Room temperature can also change significantly between day and night, regardless of the season.

You should also keep in mind that everyone has a different sense of warmth. Your baby might, for example, feel more comfortable in a baby sleeping bag with a higher TOG rating. To make sure the Sleeping Bag and Clothing Line are right for the room temperature and your child, you should measure your baby's body temperature - here's how:

Place two fingers on your child’s neck at the neckline.

What TOG ratings are available?

The TOG ratings are designed for specific room temperatures : your child’s sense of warmth and the room temperature also determine what your child should wear in the Sleeping Bag. We’ll show you which TOG rating is right for each situation:

0.5 TOG

The Sleeping Bag with 0.5 TOG is perfect for warm summer nights at room temperatures above 24 degrees. It is unlined and offers maximum breathability to reduce overheating and sweating on hot nights. A Sleeping Bag with a low TOG rating of 0.5 provides minimal insulation, which means it retains less heat. It is also lightweight and compact, making it perfect for travel or backpacking.

A 0.5 TOG offers versatile uses, as it can also be combined perfectly with a warmer Sleeping Bag as an extra layer during colder seasons.

The Sleeping Bags are made from skin-friendly materials such as cotton or bamboo, which are not only gentle on the skin but also durable and easy to care for.

The 1.0 TOG rating is versatile, as the Sleeping Bags are flexible enough to adapt to changing temperatures.

Although they provide slightly more insulation than Sleeping Bags with a lower TOG rating, 1.0 TOG Sleeping Bags are still made from breathable materials to allow good air circulation and prevent overheating.
As with all Sleeping Bags, the quality of the materials is especially important. High-quality fabrics like cotton or bamboo feel pleasant against the skin and improve sleep comfort.
