Somewhere in June, most people take the duvet off the bed and do not think about it again until October. That is one option. It is not the only one, and it is not always the most comfortable one.
The short answer: you do not need a duvet insert in summer, but the cover can still earn its place. Those are two different things, and confusing them is why so many beds end up either too hot or too bare.
Cover and Insert Are Not the Same Thing
A duvet insert is the filled part that provides warmth. A duvet cover is the fabric shell that goes around it, like a pillowcase for your duvet.
The insert is what makes a bed hot in July. The cover is two layers of cotton. On its own it is closer to a very light blanket than to bedding you would sweat under.
This distinction is the whole answer to the question, and most summer bedding advice skips it.
Three Ways to Use a Duvet Cover in Summer
| Setup | How warm | Suits |
|---|---|---|
| Cover with no insert | Very light | Hot nights, warm bedrooms |
| Cover with a light insert | Moderate | Air conditioned rooms |
| Cover folded at the foot | None until needed | Nights that cool before morning |
Empty cover as a light layer
Using the cover with nothing inside gives you a soft cotton layer with almost no weight. Our muslin duvet covers are two layers of loosely woven cotton, so air passes through rather than being held against you.
For a lot of hot sleepers this is the summer setup. You keep the look of a made bed without the heat of a filled duvet.
Cover with a genuinely light insert
If your bedroom is air conditioned, the room can get cooler overnight than the outside temperature suggests. A light summer weight insert inside the cover handles that.
The mistake to avoid is leaving the winter insert in. That is the single most common reason people decide duvets do not work in summer.
Folded at the foot
Sleep with sheets only and keep the covered duvet folded across the end of the bed. If the room drops before morning, it is there. If it does not, you never touched it.
The Practical Argument: Washing
There is a reason to keep the cover on the bed that has nothing to do with temperature.
Summer means more sweat and more washing. A duvet cover goes in the machine easily. A bare insert does not, and washing one regularly is neither practical nor good for it.
If you sleep directly against your duvet all summer, the insert takes the wear. If you keep a cover on it, the cover takes the wear and washes weekly.
When You Genuinely Do Not Need One
Being straight about this: if you sleep under a muslin blanket or a muslin quilt in summer, you do not need a duvet cover as well. Those are finished pieces that work on their own.
The duvet cover makes sense if you already own an insert and want one piece of bedding that carries through every season, or if you want the fitted sheet and pillowcases that come with the set.
What Comes in the Set
Each set includes the duvet cover, a matching fitted sheet and two pillowcases, so the bed works as one piece rather than assembled from parts.
Sizes run Twin 66 x 88, Twin XL 66 x 90, Full 80 x 90, Queen 90 x 90, King 104 x 91 and California King 104 x 95 inches.
Colors are Natural Color, White, and four woven stripes: Sage Green, Anthracite Grey, Taupe and Terra Cotta. The stripes are woven in low contrast, so from across the room they read as texture rather than pattern.
Why Muslin Rather Than Percale or Sateen
Duvet covers usually come in tighter weaves. Percale is crisp and cool to the touch but dense. Sateen is smooth and heavier still.
Muslin goes the other way. The weave is deliberately open, so the cover has almost no thermal presence of its own. In summer that is the point: you want the cover to add fabric without adding warmth.
The trade is appearance. Muslin has a relaxed, slightly crinkled surface rather than a crisp hotel finish. It also needs no ironing, which most people count as a gain.
Building the Rest of the Summer Bed
Start with breathable muslin bed sheets as the base. Add the duvet cover as your top layer, with or without an insert depending on the night. Keep a muslin blanket nearby for the hours before dawn.
The aim is a bed you can adjust rather than one that stays the same regardless of the temperature.
Care
Wash the cover alone the first time. Use a gentle cycle at 86°F (30°C) and tumble dry on low heat. If air drying, dry it naturally in a well ventilated area and avoid stretching the fabric while wet.
Do not use bleach and do not dry clean. Avoid washing with jeans or anything that has small hooks, which can pull at the weave. Muslin softens with every wash and needs no ironing.

The Bottom Line
You do not need a duvet insert in summer. You may still want the cover, either empty as a light cotton layer, with a summer weight insert in an air conditioned room, or folded at the foot of the bed for the early hours.
The washing argument is the underrated one: a cover goes in the machine every week, a bare insert does not. Our muslin duvet cover sets are organic Turkish cotton and ship from our small family business in Florida.
Frequently Asked Questions
Do you need a duvet cover in summer?
You do not need the insert, but the cover can still be useful. Used empty it works as a very light cotton layer, and it keeps a duvet insert clean when you do use one.
Can you use a duvet cover without a duvet inside?
Yes. An empty muslin duvet cover is two layers of loosely woven cotton, which makes it closer to a light blanket than to filled bedding. Many hot sleepers use it this way through summer.
Is a duvet cover too hot for summer?
The cover itself is not what makes a bed hot. A winter weight insert is. Leaving that insert in through July is the most common reason people find duvets uncomfortable in summer.
What comes in a Naturloom duvet cover set?
Each set includes the duvet cover, a matching fitted sheet and two pillowcases, in sizes from Twin through California King.
Is muslin better than percale for a summer duvet cover?
Muslin has a more open weave, so it adds less thermal presence than percale or sateen. Percale feels crisper and more hotel-like. Muslin has a relaxed texture and needs no ironing.
