15 degree can I cover the duvet?

How much temperature can a 500-gram duvet cover?

This is my answer. The suitable temperature of 500g duvet is about 15 to 20 degrees, because 500g duvet is a relatively thin duvet, which can only be covered when, er, the seasonal weather is not too serious. If it is really cold, it should be quite explosive. He can't cover it.
