Summer duvet / Lightweight duvet / 4.5 tog duvet

4.5 tog Hungarian goose down duvet | scooms

A 4.5 tog duvet is the ideal tog rating for a summer duvet. The lower the tog rating, the less warm the duvet, so a tog rating of at least 7.5 tog and lower is the best tog rating to choose for a summer duvet. The right summer duvet or lightweight duvet can help hot sleepers keep cool and sleep more comfortably during the summer months and throughout the whole year.

Summer duvet tog ratings

The tog rating of a duvet explains the amount of warmth that the duvet will provide. 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 spring and autumn months.

An all seasons duvet can be a great investment, giving you options for each season of the year; a 9 tog spring and autumn duvet, a 4.5 tog summer duvet and the option to combine the two duvets to make a 13.5 tog winter duvet.

Summer duvet materials & breathability

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 of the summer duvet materials. A summer duvet with good breathability will help any moisture from sweat to escape more easily. Naturally breathable duvet fillings like goose down, offer up to four times better air circulation than synthetic duvet fillings.

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

 

Summer duvet construction

The construction of a summer 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 duvet filling 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.

Lightweight duvets

Lightweight duvets and bedding can help you to have a better night’s sleep for a variety of reasons - if you get too hot when you sleep or suffer from night sweats; 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. 

lightweight duvet can come in a variety of tog ratings. A heavy synthetic duvet can 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. 

 

Down duvet fill weight

The higher the fill weight, the heavier the duvet. However, a heavy duvet doesn't necessarily 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 duvet fill power

Down-rich duvets are a great choice as a lightweight duvet as they 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 a more lightweight duvet filling.

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 more insulating and lighter weight duvet.  

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 cool and comfortable!
