Choosing the right duvet weight depends on how warm you naturally sleep, how warm your bedroom is, and whether you want one duvet for most of the year or different options for different seasons.
At Devon Duvets, our duvets are made with breathable natural fillings, including wool and plant fibres, so they do not behave in quite the same way as synthetic, feather or down duvets.
Instead of simply trapping heat, they help warmth and moisture move more naturally around the body. This is why we describe our duvet warmth as a fluctuating tog equivalency rather than a fixed tog rating.
1
Think about how you sleep
Are you naturally warm at night, or do you often feel the cold? Your own body temperature is one of the biggest clues when choosing a duvet weight.
2
Think about your bedroom
A well insulated bedroom, a warmer home or a south-facing room may need a lighter duvet than a colder bedroom or older property.
3
Think about the season
Some people prefer one versatile duvet for most of the year. Others sleep better with lighter and warmer options for different seasons.
Why tog works differently here
Why our duvets have a fluctuating tog equivalency
A traditional fixed tog rating measures how well a duvet insulates. This works well for many synthetic or feather duvets because their warmth is more fixed.
Our 100% natural fillings are different. Wool, alpaca and our plant-based Botanic filling are breathable, which means they can help retain warmth when you need it, while also allowing excess heat and moisture to escape.
This can help you feel more comfortable through the night, especially if you often wake up feeling too hot or too cold.
When choosing your duvet, it is helpful to think about:
whether you are a warm or cold sleeper
how warm your bedroom is
the season you want the duvet for
whether you prefer a lighter or more substantial feel
whether you want one duvet or seasonal flexibility

British Wool Duvets
Choosing a British Wool Duvet
Our British wool duvets are naturally breathable, insulating and temperature regulating. They are available in three weights, giving you a choice between lighter summer comfort, versatile year-round warmth and extra winter cosiness.
Wool is a wonderful choice if you want bedding that feels warm when you need it, but still breathable through the night.
British Wool Duvet weights
These are the three main wool duvet weights and when each one is most suitable.
300gsm | 4-7 togs
Lightweight Wool Duvet
This is our lightest wool duvet. It contains one layer of wool and is best suited to warmer months, warmer bedrooms or those who naturally sleep hot.
Choose this if:
you want a summer duvet
you are a warm sleeper or have hot flushes
your bedroom is well insulated
you prefer a lighter, cooler duvet
you live in a warmer part of the UK
600gsm | 8-14 togs
Medium Weight Wool Duvet
This is our most popular wool duvet and a good choice for many customers for much of the year. It offers more warmth than the Lightweight duvet, while still allowing the breathability of wool.
Choose this if:
you want one wool duvet for most of the year
you want a cosy but breathable duvet
your bedroom is not especially warm
you live in a cooler area
you want our most versatile wool option
900gsm | 14-18 togs
Extra Warm Winter Weight Wool Duvet
This is our most substantial wool duvet. It is warmer and physically weightier than our other wool options.
Choose this if:
you really feel the cold
you sleep in a very cold bedroom
you like to keep your bedroom very cool at night
you live in a particularly cold area
you want a very warm winter duvet
you like a little more weight
Most flexible wool option
All Seasons Wool Duvet Set
For the most flexibility, our All Seasons Set includes one Lightweight Wool Duvet and one Medium Weight Wool Duvet.
You can use the Lightweight duvet in summer, the Medium Weight duvet in cooler months, or both duvets tied together for extra warmth in winter.
All of our wool duvets have ties attached, so any two wool duvets of the same size can be fastened together.
This is the best choice if you want your bedding to adapt through the year.
British Alpaca Duvets
Choosing a British Alpaca Duvet
Our British alpaca duvets are naturally breathable and temperature regulating, with a lighter, cooler feel than our British wool duvets.
Lightweight Alpaca Duvet
200gsm | 3-6 togs
best for summer use
good for warm sleepers
physically lighter than wool
cooler than our Lightweight Wool Duvet
Medium Weight Alpaca Duvet
400gsm | 7-10 togs
natural warmth without too much weight
good for warmer or well insulated bedrooms
warmer than a summer duvet
cooler than our Medium Weight Wool Duvet
Botanic Duvets
Choosing a Botanic Duvet
Our Botanic duvets are our plant-based duvet range. They are breathable, moisture wicking and generally cooler than our wool duvets.
They are a good choice if you want a natural, plant-based option or if you are looking for a cooler duvet feel.
200gsm | 2-4 togs
Ultralight Botanic Duvet
Choose this if you want our coolest duvet, need a summer duvet, sleep hot, have a warm bedroom or want a plant-based option.
400gsm | 4-6 togs
Lightweight Botanic Duvet
Choose this if you want a light duvet for spring or early autumn, need a little extra warmth in summer or sleep warm but do not want the coolest option.
600gsm | 6-8 togs
Medium Weight Botanic Duvet
Choose this if you want the warmest Botanic option, are a warm sleeper in winter, or want a breathable duvet for spring and autumn.
Simple summary
Still choosing? Start here.
For hot sleepers, look at Lightweight Wool, Ultralight Botanic or Lightweight Alpaca.
For one duvet for most of the year, look at Medium Weight Wool or the All Seasons Wool Duvet Set.
For cold sleepers, look at Medium Weight Wool, Extra Warm Winter Weight Wool or the All Seasons Wool Duvet Set.
For plant-based bedding, choose from the Botanic duvet range.
For the most flexible option, choose the All Seasons Wool Duvet Set.
Choosing the right duvet weight is personal. Your body temperature, bedroom temperature, home insulation and seasonal needs all make a difference.
A final note on gsm
GSM means grams of filling per square metre. It helps describe how much filling is inside the duvet.
With natural duvets, gsm is useful because the filling is breathable and responsive. A higher gsm generally means more warmth and a more substantial feel, while a lower gsm generally means a lighter and cooler duvet.
That is why we use gsm alongside an approximate fluctuating tog equivalency, rather than asking one fixed tog rating to do all the work. Poor little tog. It tried.
