You’ve probably heard of tog ratings, but do you know what tog really means?

Simply put, it stands for Thermal Overall Grade. It a measure of the thermal insulation of your duvet which in turn tells you how good a duvet will be at trapping heat underneath it and keeping you warm.

The lower the tog rating is the less heat will get trapped underneath and the higher the tog rating is the more warmth it will retain underneath it.

What is the best tog size for a winter duvet?

The tog rating typically goes from the lightest tog at 1 to 16.5, in some cases you may find an even higher tog.

For winter we recommend a duvet that is on the higher end of this from 13.5 to 15. This will keep you cosy in the colder months. If you have a duvet that is as high as or higher than 13.5 tog it will continue to be warm for around 30 minutes after you have left your bed.

You may find you need to experiment a little to be able to find a duvet with the right tog for you. If you are getting cold in the winter months but a 13.5 to 15 tog duvet is keeping you uncomfortably warm you may want to try out an all-seasons duvet, tog ratings for these go from 7.5 to 10.5. These can be a great all-around duvet that keeps you warm in the winter, cool in the summer and comfortable when the weather seems to change its mind daily.

Because tog has such a huge range we have split up our duvets to serve as a guide for you. We have split them into summer duvets, winter duvets and all seasons duvets.

For summer duvets we recommend 1.5 – 4.5 togs. For winter we recommend 13.5 – 15 togs.

Our all seasons duvets range from 7.5 togs to 10.5 togs.

We would say 18 tog might just make you too stuffy while you sleep.

Does a Higher Tog Rating Mean a Thicker Duvet?

In general, a higher tog will probably mean a thicker duvet but this is not always true. If you are comparing duvet with different fillings this may not work.

Different thermal qualities come with different fillings making the thickness needed to achieve a certain tog vary.

If you had two duvets one 7.5 tog and the other 10.5 tog you would probably assume, without looking at them, that the thicker duvet would be the 10.5 tog. If the 7.5 tog duvet were to be made with down as the filling and the 10.5 tog duvet were to be made with a hollowfibre filling you would find that the 7.5 tog duvet would be thicker.

So, remember, a higher tog does not always mean a thicker duvet.

What is the warmest duvet filling?

Duvet fillings are important in terms of the following:

  1. Warmth
  2. Thickness
  3. Weight
  4. Breathability

The most common fillings and therefore the ones you are most likely to find are hollowfibre, microfibre and down.

Hollowfibre filling

Hollowfibre filling is made using extremely thin strands of polyester that tangle around each other to create padding that is similar to cotton wool.

Hollowfibre is the most versatile, it’s breathable and lightweight. It will keep you warm without added weight and thickness and is naturally hypoallergenic.

Microfibre filling

Microfibre filling is made from polyester and is very soft. It is frequently used to be a synthetic substitute for down as the feel of it and its qualities are very similar to down but is cruelty-free  and will not trigger any allergies.

Down filling

This type of filling is simply either one or both goose down and feather and/or duck down and feather. This filling has been used for a very long time as it is really warm to sleep under.

The downside of this type of filling is that there is animal cruelty to consider alongside the fact that the feathers will escape. This can trigger your allergies if you have them.

What is the best duvet material for cold sleepers?

There are many different types of material used as duvet material with the most common being, polyester, polypropylene, cotton and microfibre. The material of your duvet can be what makes a difference in whether or not you overheat at night.

Cotton

If you are opting for a cotton cover you will want to find something with a thread count between 230 and 300 as this has a much smoother feel than lower thread counts and will maintain this softness for a long time.

There is a variety of different types of cotton and we believe that organic cotton is a wonderful choice as it is certified organic to agricultural standards and is naturally hypoallergenic.

Cotton naturally will regulate the body’s temperature making it a great choice for any season.

Polyester

Another great option is polyester. Unlike cotton, it is a synthetic material however you will not need to worry about thread count in the same way. Polyester is a fairly smooth material that is actually even more long-lasting and durable than cotton.

Polyester is also much more inexpensive than cotton. Making it a good alternative.

Polycotton (50-50)

50-50 cotton-polyester, otherwise known as polycotton, is a mix that is true to its name. It is 50% cotton and 50% polyester. This makes this material the perfect balance between the two.

The material feels similar to a 230-thread count cotton cover and its durability lands between that of cotton and polyester.

Polypropylene

Polypropylene is a plastic polymer that is the least expensive duvet cover material. At Bedding Comfort Store we use teabag variety polypropylene that will last for years even with intensive use.

Where do hotels buy their bedding?

Microfibre

Soft-touch duvets are another name for microfibre duvets and this is for a very good reason. Microfibre covers are made using ultra-low pile soft microfibre and have great breathability. It is a particularly smooth material that is almost as durable as polyester and lighter than polyester and cotton.

Wool

Wool is naturally flame resistant and would take an incredible temperature of 1058 degrees Fahrenheit to light.

It is a material that is adaptable to different body temperatures which could make it perfect for people who share a bed.

Silk

Silk, despite being a luxurious choice, is also natural, low-maintenance and easy to wash. A silk duvet will wick heat off your body as you sleep to cool you down. At the same time, it will trap heat underneath when you feel cold. This has a great effect of keeping you warm at night but not uncomfortably so.

Silk pillowcases are specifically great for the health of hair. It can stop your hair from drying out overnight leaving you frizzless in the morning.

Linen

Linen can absorb moisture without holding onto the bacteria. It is also a great heat conductor that gets more pliable and stronger every single time you wash it. This makes it the perfect material for you if you are looking for something long-lasting and biodegradable.

After you have chosen your duvet it is vital that you understand what you have chosen, how to care for it and how to wash it.
