It gives you an idea of how much body heat will be retained by the duvet. The higher the tog rating, the warmer the duvet. So a 4.5 tog is lighter making it perfect for the hotter seasons when you tend to get sweaty. A 13.5 or a 15 tog duvet would be ideal for the cooler months to keep you nice and snug. A 10.5 tog is somewhat in-between and is used for all seasons, whether its hot or cold. It's all down to preference as to how warm you want to be.  What makes a good duvet? Definitely not the packaging! You need to look at the type of filling used in the duvet to determine its quality. You have the classic hollowfibre, to the microfibre to the feather and down. Don't worry, we'll explain everything for you so you understand the difference in filling to choose the perfect duvet for you.  Different types of fillings in your duvet Our hollowfibre and microfibre duvets fall into the synthetic category often used by people who suffer from allergies and asthma. The silky soft duvet is the closest synthetic alternative to a natural down duvet giving you extra warmth and ensuring a featherweight feel. Its an affordable option so you don't have to break the bank. Our goose feather and down duvet is a natural choice filled with long goose feathers making the duvet thermally efficient at retaining your body heat.
