TOG Values

Tog value is an industry term for measuring the warmth of a duvet. The higher the tog value, the warmer the duvet – although keep in mind that this has nothing to do with the weight of the duvet. The tog value is measured in units of thermal resistance.

For example, if a duvet has a tog value of 4.5, then it would be more suitable for summer. If a duvet has a tog value of 13.5 and above, it will be superb for the colder months.

You can use the tog table below as a guideline when choosing your duvet:
