Summer Duvet Buyers Guide

Having one hefty duvet all year round is just not an option for most people. It makes no sense to endure sleepless summer nights of tossing and turning, trying to find the coldest part of the bed (which we all know doesn't exist) when you can take your sleep into your own hands and purchase a summer duvet.

So, what's the best summer duvet for keeping you cool? Well, there is no one answer to this question, but instead there are a few different factors you need to take into account. Therefore, while everyone has different preferences, we hope this guide will help you make the right choice for you when it comes to buying a summer duvet.


Tog, which stands for 'thermal overall grade', is a measurement of thermal insulation. The main rule to remember is the higher the tog the warmer the duvet.

Anything between 1-7 is recommended for summer. Therefore, you may be thinking "great, 1 tog it is", however it's important to remember that more often than not you're kicking the duvet off to start with but are searching for it in the night when you begin to feel a little colder. It’s good to find a happy medium which most say is a tog of 2.5 to 4.5.


There are two types of duvet filling: natural and synthetic. If you're looking for a natural summer duvet, one of the best options for keeping you cool is silk. It’s much more breathable than other materials and is known for adapting to your body temperature and the temperature of the room, helping to get it just right for a good night’s sleep. It is also naturally hypoallergenic, so a better option over feathers or down.

Synthetic fillings are also hypoallergenic; important to look for if you don’t want allergies keeping you awake on top of the heat. Microfibre filling is usually a good synthetic option as they are lighter than feather-filled duvets, but the fine fibres still give it a soft, luxurious feel. 

The good thing about synthetic filling is it's more absorbent of sweat, so you won’t feel much dampness throughout the night, and they are easier to wash. It’s also distributed evenly throughout the duvet, unlike some natural duvets where filling can cluster, making you hotter in some areas than others. However, they won't last as many summers as natural filling.


The duvet cover also needs to be considered when thinking about your summer duvet as some materials, like cotton, are more breathable. Warmer cover options such as flannel and microfiber should be avoided in the hotter months.

It's also important to choose a cover that's soft as there's nothing worse than rolling over in the heat and being irritated further by a scratchy cover.

Combine duvets

If you have limited space and don’t want to buy multiple duvets for the different seasons, one idea is to buy duvets that can be linked together. This is usually done using ties or buttons and means you can choose two duvets with varying togs to create your ideal duvet that you can combine to keep you warm in the winter, and separate to keep cool in the summer.

Although less common, some duvet companies actually offer a duvet that has different tog ratings on either side. So, if your partner doesn’t get as warm and uncomfortable as you, they may want to opt for a higher tog on their side, while you’ll sleep soundly next to them with your lower tog rating.
