What is the TOG-Value?
The TOG (Thermal Overall Grade) is a measure for thermal resistance of textiles. The higher this value, the higher the thermal behaviour of the quality.
The “correct” TOG-VALUE depends mainly from the room temperature.
The recommended temperature for a children room/sleeping room is 16 – 18° degrees.
Which TOG-VALUE should be applied is indicated as below:
|0.5 TOG:||Summer sleeping sack for hot temperatures from 22° C on|
|1.0 TOG:||Leichter Schlafsack bei Temperaturen von 19-24°C|
|1.5 TOG:||Moderately heavy sleeping sack for temperatures from 18 to 21°C|
|2.0 TOG:||Lined sleeping sack for temperatures from 17 to 20°C|
|2.5 – 3 TOG:||Heavily lined sleeping sack for temperatures under 16°C|
This shows the deficiency of this system, so popular presently. It is measuring only the thermal resistance of the material.
The TOG-Value does not adequately consider if the material has only been knitted or also has been fulled afterwards.
It is not important for the TOG- Value if the garment has long or short sleeves or what a child wears under its sleeping sack.
This however is absolutely important for the well-being and is not to be judged by the TOG-Value.
The weight of a cloth indicated in grams refers to one running meter, but does not consider the width, which may vary considerably.
A direct comparison therefore is only possible with other standards and special knowledge.
is a unit for measuring the fineness of fibres. One Micron is a thousandth of a millimeter.
The smaller the Micron rate the finer the fibre. We use fine, natural merino wool from 19,5 Micron on.
This is very fine and comfortable on the skin.
