The TOG Rating and the Evolution of Baby Sleeping Bags

What is the TOG Unit?

The world of baby care has always been focused on ensuring the safety and comfort of infants, especially when it comes to their sleep. In this context, the TOG unit (Thermal Overall Grade) has played a central role. Created in the 1960s, this unit was designed to measure the thermal resistance of textiles, particularly bedding and nightwear. Since then, TOG has become a key reference for evaluating the insulating effectiveness of baby sleeping bags.

The History and Creation of the TOG Unit

The origin of TOG traces back to research on thermal comfort in nightwear and bedding. In the mid-20th century, British researchers sought a way to quantify the ability of textiles to retain body heat. This led to the development of the TOG unit, which measures a fabric’s thermal resistance.

TOG quickly became popular due to its simplicity and practical usefulness. It allowed parents to more easily choose products suitable for various seasons and climates, based on how well these items could keep their baby warm or cool.

How the TOG Unit is Used and What it Means

TOG is a measure of thermal insulation. The higher the TOG, the more insulating the fabric is. For babies, this unit helps determine which sleeping bag is suitable for different room temperatures. For example, a sleeping bag with a TOG of 2.5 is ideal for a room with temperatures between 16 and 20 degrees Celsius, while a 1.0 TOG sleeping bag is better for temperatures between 21 and 23 degrees Celsius.

Is There a Better Solution Today Beyond TOG?

 

Why Don’t Zizzz Baby Sleeping Bags Use TOG?

However, not all baby sleeping bags rely solely on TOG for comfort and safety. This is where the innovative concept of Zizzz baby sleeping bags comes into play. Instead of relying on static thermal insulation, these sleeping bags feature a patented Swisswool filling, a material used in professional skiing due to its natural body temperature regulation properties.

 

Benefits of Wool Over Polyester

Wool, a natural material from sheep, has exceptional insulating properties. Unlike polyester, a synthetic fiber made from petroleum products, wool offers superior breathability and moisture-wicking capabilities. This means that wool can absorb moisture from the baby’s body and release it into the air, keeping the baby dry and comfortable throughout the night.

Additionally, wool regulates body temperature very efficiently. It keeps the baby warm in cold weather and cool in hot weather, which is particularly beneficial for nights when the temperature fluctuates. Furthermore, wool is hypoallergenic and causes fewer allergic reactions compared to synthetic materials like polyester.

What Would the TOG Value Be for Our Swisswool Baby Sleeping Bags?

Thanks to these unique properties, our Swisswool baby sleeping bags have a TOG range from 1.5 to 3.5, allowing them to be used year-round in various environments.

Durability and Comfort

Wool is also more durable than polyester. It maintains its insulating properties and shape after repeated washing, unlike polyester, which can flatten or form lumps. This ensures long-lasting comfort and functionality.

Usable All Year Round

The Zizzz baby sleeping bag, with its Swisswool filling, stands out for its ability to regulate temperature without the need for a specific TOG. These sleeping bags can be used almost all year round, except on very hot summer days when a special summer sleeping bag is recommended.

And for the Hottest Summer Periods?

For the hottest nights, Zizzz also offers summer sleeping bags made solely from organic cotton, ensuring softness and comfort without the risk of overheating. These sleeping bags have a TOG value between 0.5 and 1.

Conclusion

The TOG concept revolutionized how parents choose baby sleeping bags by providing a clear measure of thermal insulation. However, advances in natural materials, like the Swisswool filling used by Zizzz, show that it is possible to go beyond TOG to provide superior comfort through natural temperature regulation. Zizzz baby sleeping bags perfectly illustrate this evolution, combining innovation and tradition to ensure the best possible sleep for little ones.
