A duvet with a 4.5 tog rating or less feels like a soft, quilted sheet. It is thin and light to the touch – ideal if you’re in a very warm room or if you get hot at night.
The best 4.5 tog lightweight duvets can also useful as an extra duvet. They pack up very small, especially down duvets, and can be kept in a cupboard for an extra layer on colder nights, or just to use on their own on the hottest nights of the year.
Duvets which are less than 7 togs are called ‘lightweight duvets’, or ‘summer duvets’.
At Duvet Advisor, we don’t really like to use the term ‘summer duvet’ or ‘winter duvet’ as to be honest, it truly depends on how warm your house is and what your own body temperature is like. A centrally heated bedroom in winter is often warmer than your bedroom in summer, so we don’t find these terms very useful.
‘Lightweight duvet’ is a better term although this will also depend on the filling material of the duvet. Down duvets are always lighter than feather duvets, and synthetic, down and feather duvets tend to be lighter than wool duvets.
Overall then, think of the ‘tog’ rating as simply how warm the duvet will keep you, and this one will keep you cool.
