What is a Cooling Duvet Insert?

Cooling duvet inserts are specially made with moisture-wicking features. The type of fibers used and the weaving style is such that it provides maximum breathability. These beddings help the sweat to spread out and dry within minutes to provide a cool environment.

Another important aspect of a cooling duvet insert is that it is lightweight. Despite its thickness and filling, it is constructed in such a way that it does not trap heat. Cooling duvet inserts may use varying filling materials.

Some duvet inserts contain synthetic fibers, while others may be filled with down or feathers. If you want the one that keeps you cool, avoid real down as it can contain warmth for a prolonged period.

There are several other factors that you need to look into while making your final purchase. Before that, let us go through the benefits of using a cooling duvet insert.

Benefits of Using a Cooling Duvet Insert

Easy Cleaning and Care

First of all, your duvet insert wouldn’t require cleaning too often. Why is that? It has a protective layer of duvet cover that keeps all types of dirt out. It means that the insert is never exposed to dust, body oil, sweat, or any other particles.

That said, you must know that you will have to change the cover regularly, replacing it with fresh ones. It is so because it is the outer layer that tends to get dirty. Apart from that, you can wash the insert once in 2-3 months if required.

Note: Adhere to the washing instructions that are usually given on the cooling duvet insert label. Most of them can be machine-washed, while some may require dry cleaning.


Duvet inserts are always covered, do not require much cleaning, and are not exposed to the external environment. It means they are highly durable. Moreover, quality materials do not tear or fade away easily, even after several years.

What’s more? The materials used for these inserts often become softer with every wash. Thus, keeping you from buying another one for a prolonged period. However, silk requires careful laundering.

Versatile DesignBenefits of Using a Cooling Duvet Insert

If you opt for cooling duvets over other types of blankets or comforters, you can have a new one every week. No, you will not need to buy a new duvet insert so often. You can change the duvet covers whenever you want.

You will have a diverse range of colors to choose from, without actually having to buy so many comforters. Swap among patterns and designs all you want!

Fill Material Diversity

Duvet inserts are filled with varying types of materials. You can choose your preferred one from natural filling such as cotton, bamboo, and eucalyptus to the different synthetic fibers. It gives a wider range of choices for those looking for hypoallergenic yet cool comforters.

Cooler sleeping environments are the best since your body tends to heat up in the middle of the night. If you do not have cooling beddings, the fluctuation in body temperatures may ruin your sleep. This takes us to the next benefit.


Cooling duvet inserts can naturally regulate the temperature. Materials such as silk and wool can hold moisture without actually feeling wet. These materials allow quick evaporation of sweat, providing a cool environment to sleep.

At the same time, it can trap air well to keep you warm during the cooler nights. The same goes for cotton and several other blends.


A cooling duvet insert is a healthier option than other types of comforters. Certain bacteria, mites, mildew, mold, and allergen, tend to breed in warm surroundings. This is so, especially because warm blankets and comforters are bound to hold moisture.

You will not face such a problem with a cooling duvet. It is due to the breathable nature of these bedding pieces. The constant flow of air keeps the material dry, preventing the formation of such things. That is why this is a better option, especially if you are allergic to dust and sundries.

What Should You Consider While Buying the Best Cooling Duvet Insert?

Having read the benefits of a cooling duvet insert, you may be convinced why it is a superior option. However, you are not yet ready for your final decision. There are certain things that you need to keep in mind while making your purchase. Let’s have a look!

Fill Power

It is the direct indication of the capacity of insulation provided by a duvet. In clear terms, fill power refers to the space taken up by one ounce of the filling. Here, you are looking for a cooling duvet insert. Hence, the lesser the fill power, the cooler it is.

If you are a hot sleeper, you can go with an insert that has less than 400 or up to 600 units. The former one is ideal for summer nights as they are extremely lightweight and have a low loft. Duvet inserts having fill power between 400 to 600 will be slightly thicker but still appropriate for early spring and autumn.

Anything more than 600 will not be termed as a cooling duvet insert; instead, it will be an insulated one.

Quality and Filling MaterialHOLLOW MICROFIBER FILL

As mentioned earlier, duvet inserts may have varying types of stuffing. The most common are Goose Down and Duck Down. Both of these materials feature naturally high insulation levels. They should be avoided if you are looking for a cooling duvet.

Cotton, wool, silk, eucalyptus, bamboo, etc. are another category of natural fibers. However, these are soft, highly breathable, and feature moisture-wicking qualities. These are the best materials for a cooling duvet insert. The same goes for a down alternative.

Design and Construction

Duvets have a diverse range of stitch designs. The most common ones are box-stitch and baffle-box, both of which hold the filling in place. However, the former may not retain the loft of fluffiness as well as the latter. It is so because, in the baffle-box, the top layer of the insert is attached to the bottom.

Other types are channel construction and gusset. Among all of the mentioned designs, the baffle-box style is the most breathable. It connects the bottom and the top of the material in a criss-cross way forming cubes. The filling in such duvets has enough space to float and let the air pass.


It is a type of measurement used to determine the warmth of a duvet. It can be as low as 1.5 to as high as 15 units. A lower tog means that the duvet will trap less heat, perfect for hot sleepers. The ideal cooling duvet insert for summers will be somewhere between 2.5 to 6 togs.

If you want one for the spring or autumn seasons, you may go for an insert with a 7 to 10.5 tog rating.

Washing Conditions

Washing Conditions

You will want a duvet that is easy to maintain. While you can remove the covers and wash them whenever you want, it is not so with the inserts. However, most of the cooling duvet inserts are machine-washable. It is so because of the microfibers and natural materials used in them.

Note: If you want to get rid of a stain, try moving the filling and hand-wash the patch. Additionally, carefully read the washing instructions and try to air dry your duvet insert.

Shell Material

Similar to the filling, shell material also varies among the duvet inserts. While cotton and polyester are the most common ones, eucalyptus and bamboo fabrics are also available.

Cotton shell is considered to be one of the most breathable ones. Additionally, it is soft as well as durable. On the contrary, polyester is known for trapping heat. Thus, it is not preferable for hot sleepers. Both eucalyptus and bamboo are known to have moisture-wicking and temperature-regulating qualities.

Other factors to deliberate over include size, brand, and pricing. You must choose the cooling duvet according to your bed (twin, full, queen, king, etc.). When it comes to pricing, it may range from as low as $85 to over $1000. Furthermore, each brand renders varying warranty policies. Make sure the features of the duvet match the price.

                          Precautions to Take After Buying a Cooling Duvet Insert—The Aftermath

                          Having gone through the exemplary features of the top 12 cooling duvets, you may have surely chosen your favorite one. However, your job does not end here. Once you purchase the ultra-soft, hypoallergenic comforter, you need to take the small but necessary steps to enhance its life.

                          Here are a few measures that can help you maintain the quality of your cooling duvet insert for a prolonged period.

                          Daily Care

                          Regularly fluff your duvet insert. All you need to do is hold it from one end and shake it well. It will ensure that the filling spreads throughout the comforter even if there is clamp-formation.

                          You must air the insert or bake it under the sun for an hour or two. Doing this 2-3 times in a month will help remove any unpleasant body odor caused due to sweating and moisture.

                          If you can, prefer dry cleaning or professionally laundering your cooling duvet. Though you can opt for machine-washing, it will somewhat affect the quality over time.


                          Leaving the duvet insert exposed to moisture may ruin it after some time. To maintain its premium quality and texture, you must store the comforter in a non-woven bag, which is breathable.

                          Storing it in a plastic cover may not allow ventilation, leading to mildew or mold formation. Additionally, make sure that the storage area, as well as the bag, is dry.


                          Apart from taking extra steps, there are some that you need to avoid. Do not sit or lay down on the comforter. Though duvet inserts contain a strong filling, it may break if repeatedly compressed or crushed. This will further lead to your comforter losing its fluffiness.

                          Human skin naturally excretes oil. You need to make sure that you either cover the cooling duvet or wash it once every month or two. It will prevent your comforter from turning yellow due to dust and oil exposure.


                          Getting a complete, soundless sleep is highly essential for your mood as well as health. Here, your bed and comforter play a prominent role. Your bedding will be in direct contact with your skin, which is why you cannot compromise on its quality.

                          Apart from that, there are several factors that you need to keep in mind while choosing your duvet. Its weight, construction, shell, and filling materials are a few of the aspects you must keep in mind while purchasing. These features will determine the cooling ability of the duvet insert.

                          If you are a hot sleeper, a cooling duvet insert, which is also hypoallergenic, is best for you. It will keep dry and prevent the formation of mites or dew that may arise due to moisture.

                          So, what’s the hold? Say goodbye to the nightly sweating and hello to a deep, comfortable sleep throughout the year!
