Duvet has lost its label how do I know what Tog it is to replace!

I am pretty sure its not a 13.5 tog but - it could be 3.5 or 10 ? HOw would I know!

Does it have to be exactly the same one?

Well - what I have works, if its a 3.5 tog and I buy a 10 it maybe too hot?

Or perhaps 10 is a happy medium tog for winter and summer ?

Well I think the thicker it is the higher the tog, my sons is a lightweight duvet so not to thin not to thick and that's a 7.5 tog (if that helps)

A 3 tog will be very thin and light. 10 a bit more substantial

our summer duvet is 4.5 and the winter one is 13.5.

If yours is 3.5 it'll be very thin!

I think in the past I have bought two duvets which can be clipped together - one 3.5 tog, the other 10 tog, which together obviously makes a 13.5 tog duvet.

I think I use the 10 tog all year round, unless very hot in the summer.

10.5 is standard.
An old duvet may not be as warm it it should anyway, so compatible your old label to a new one may not work anyhow.
3.5 is very thin
13 is really thick!

Ok so perhaps my current one is 10 tog - as it works for both and I will replace with that - its a lot of money - difference, and I am going for the white company = thank you
