This is a very interesting question with a number of variables affecting each specific situation. First of all, each individual person has his or her own preferred sleeping temperature. Some people are ‘hot sleepers’, which means their body generates a lot of heat, and therefore they do not like a quilt that is too thick. Conversely, ‘cold sleepers’ do not generate a lot of body heat when sleeping, and so often desire a quilt with a thicker layer of wool fill inside.
Essentially, one needs to realise the quilt itself doesn’t generate heat – what matters is which type of sleeper you are. Aumore Wool 100% premium Downs wool quilts breathe incredibly well, which means your quilt won’t get too warm in the summer, nor too cold in the winter. However, we always recommend you choose the level of wool thickness (300g/500g/600 grams per square metre) you think will best suit the type of sleeper you are.
