Lightweight bedding
Lighter bedding can help you to have a better night’s sleep for a variety of reasons - if you get too hot or suffer from night sweats, or if you have restricted movement due to age or injury, or if you’ve had a recent operation.  A lightweight duvet won’t weigh you down awkwardly and should help you sleep much more comfortably. 

Tog ratings
The tog rating of a duvet explains the amount of warmth that the duvet will provide and is not related to weight. The lower the tog rating, the less warm the duvet, so a tog rating of at least 7.5 tog and lower will ease your sleep during the summer. A 4.5 tog duvet is an ideal tog rating for a summer duvet. A 9 tog duvet is perfect for the warmer spring months.

An all seasons duvet could be a great investment, giving you options for each season of the year; a 9 tog duvet for Autumn and Spring, a 4.5 tog duvet for the Summer and the option to combine the two duvets to a 13.5 tog for the Winter.

Therefore, a lightweight duvet could come in a variety of tog ratings. A heavy synthetic duvet could provide 4.5 tog summer warmth and so can a much more lightweight goose down duvet. Check the duvet fill weight, which is the weight of the duvet filling, before you buy.

Fill weight
The higher the fill weight, the heavier the duvet. But as just mentioned, a heavy duvet doesn't equal a warmer duvet. In down or feather duvet fillings, fill power not fill weight measures the effectiveness and quality of the insulation provided. So, a duvet with high fill weight but low fill power will be heavy and provide poor insulation. 

(Note that 'GSM' means the weight of the filling within a square metre.)

Down fill power
Down-rich duvets are a great choice as they are lightweight but still provide superior warmth and temperature regulation. Down is the best natural insulator and offers the greatest warmth to weight ratio. Goose down has a larger number of fluffy filaments than duck down or feather which means it is more lightweight.

Down fill power measures the quality and effectiveness of down and feather. The fluffier the down is, the greater the number of air chambers and therefore, the more effective it is at insulating. So a higher fill power provides a lighter and more insulating duvet.

Breathability and materials
The best summer duvets will help you avoid poor sleep and waking up sticky and tired. As well as the tog rating, you need to consider the breathability duvet materials. A duvet with good breathability will help any moisture from sweat to escape more easily. Naturally breathable fillings like goose down, offer up to four times better air circulation than synthetic fillings.

Make sure the duvet casing as well as your bed linen - duvet cover, sheets, pillowcase - are 100% cotton not synthetic. Cotton is temperature regulating and sweat wicking. 

Duvet construction
The construction of a duvet can also help you manage your body temperature as you sleep. A pocket construction, such as Box or Baffle stitched, ensures that the duvet filling is evenly distributed and doesn’t all sink down to your toes. It also gives the down more space which increases fluffiness and breathability.

The scooms 9 tog duvet has extra side walls in the pockets, giving the down more space and allowing for extra fluffiness and breathability.

So, remember that a low tog rating and breathability are the most important things to consider for a summer duvet. And fill weight and fill power are the key elements to think about for a lightweight duvet. Sleep comfortably …
