9 best summer duvets with a low tog to keep you cool on hot nights

So clever old Simba has answered the question of which duvet to use and given us everything all in one product. There’s a 7 tog duvet for spring and autumn, a 3.5 tog duvet for summer and then you can put them together for full winter coverage. Simba has even colour coded them so you don’t get mixed up.

Let’s plumb the layers. The casing is made from temperature-regulating cotton that draws heat away from you when you need it. It’s made from a layer of eco-friendly modal fibres, which is super breathable and also wicks away sweat. There is also a layer of “Simba renew”, which is a green option as it’s made from recycled PET bottles and provides breathable warmth. The two-layered duvet also snaps together using poppers at each corner, making changing the duvet a bit less faff.

Panda claims its made a down-feather-like duvet without using any actual feathers. Great for Vegans, but did it pass muster in testing? The quick answer is yes – hence why it’s on this round up. The Cloud duvet is fluffy and feels premium. The 100 per cent organic bamboo casing feels hardwearing, yet silky to touch.

Why are we supposed to be excited about bamboo? Well, it’s eco-friendly in comparison to cotton thanks to the production process being much lower impact on the environment. Bamboo is also all natural, hypoallergenic, breathable and wicks away sweat. Genius. Panda goes a step further and ensures all the bamboo it uses is grown sustainably. The filling of this duvet is actually 50 per cent organic bamboo and 50 per cent nano fibre, which is a material made out of recycled bottles. This makes it possible to chuck the duvet in the washing machine, if needs be.

If you’re after a thicker summer duvet, this is a good option. It’s 10.5 tog, and what’s known as an all-season duvet. That means it’s a one-size-fits-all approach – great if you don’t have much storage for a myriad of duvets (who does?!) or you don’t want to faff about changing over every season. We found it perfect for the April evenings we used it on as it felt super snuggly and we didn’t overheat once, nor did our fussy and prone-to-overheating co-tester.

Yet another wool duvet, but this one is sourced from sheep in New Zealand. It feels slightly thicker than the Devon Duvets’ option (£170, Devonduvets.com) but you can buy this duvet in different thicknesses for different seasons if that was a dealbreaker. Obviously, we tested the summer thickness for this roundup, but it was still decently weighty. This created a nice secure feeling as we drifted off to sleep.

We liked this wool duvet for its excellent temperature regulating properties. Of course we roped in our fussy co-tester and found that both of us stayed temperate all night long. This clever duvet is perfect for those couples who cannot agree on what temperature they like to be when they sleep, as it creates your perfect temperature on each side of the bed. It’s like sleeping in a blissful cocoon. Another thumbs up goes to its hypoallergenic properties, and it’s also machine washable.

This duvet feels as pillowy as a candyfloss cloud. It’s filled with smartfil polyester fibre and modal filling, so it’s incredibly lightweight and also hypoallergenic. It allows air to flow through the duvet to keep you cool, and those modal fibres are going to help with moisture control (aka suck up your sweat).

The duvet feels luxurious thanks to the 200-thread-count cotton cover. Although we tested the 4.5 tog, it still feels pretty snug with a good drape around our body at night for that reassuring weighty feeling. Plus, we didn’t overheat, even when sharing the duvet with one other adult and one roasty toasty young child. Other points we liked was that it comes with button holes so you can partner your duvet up with another if you want to bolster the tog rating, and it also has a drawstring bag for dust-free storage. And it’s amazing value for money.

We’ve long been jealous of our children’s wool duvets, so we were thrilled to take one of our own for a spin. Wool is a fantastic temperature regulator, keeping you cool in summer and warm in winter and it’s also naturally flame retardant, so it is free from any chemicals if that’s a concern. Plus it’s hypoallergenic.

What we especially want to shout about on this duvet is that it’s not a big fluffy one – it’s substantial without loads of pillowy action. Some might like it for this, others might not. All opinions are valid. But if you want a low-profile duvet, this is a great option.

It is however nice and toasty. We were surprised how perfectly warm the duvet kept us despite not being fluffy. It also had a lovely drape to it, which made us feel extra snug. Other things we liked was that the wool on this duvet has been sustainably sourced from live sheep, and then handmade in England.

We had to rub our eyes when we saw the price of this duvet. Just how Dunelm is making kingsize duvets for sub £20 we don’t know, but it makes for a very purse-friendly purchase. Made from hollowfibre, we found this duvet incredibly soft and light to snuggle in to, yet it still offered some warmth against cooler evenings. The casing is microfibre, which is good for wicking away sweat and it’s stain resistant too.

Another plus point is that this duvet is hypoallergenic, and allergy sufferers will also benefit from being able to machine wash this one too. While we didn’t find this duvet as premium as others on this round up – it’s slightly less good at temperature control, and the seams aren’t bound – but for the price we think this is a great deal.

If you want a high-end duvet but feathers just aren’t for you, then this 100 per cent cotton one provides that bouji feeling without animals getting involved in the process. The loft isn’t huge on this duvet, as there’s no fluffy fibres inside. But it draped nicely around us to make us feel snug all night long. Although Dusk says this is lightweight, we actually found it slightly weightier than other products in this round up – for us that’s no bad thing though.

Cotton is great at helping to control your temperature, so it’s going to keep you cool on those balmy summer nights without you needing to kick off the covers. The casing is also 100 per cent cotton, and the whole duvet feels very premium and incredibly soft. Allergy sufferers will like that you can bung it in the washing machine at 40C and even tumble dry it on a low heat.

Not content with just being a lightweight summer duvet, Next has made this duvet active cooling too. The casing on the duvet is infused with heiq cool dual-action cooling technology which means it offers a cooling sensation on touch, sensing when you start to get too hot and activating to release moisture to cool you down again. It will then also sense when your body temperature has lowered and stop working so you don’t get chilly. Actual witchcraft, right?!

We loved this duvet for its high-tech features. We certainly never felt too hot under it. Did we notice the cooling effect? Not tangibly, but we suppose that’s sort of the point. We were asleep, after all. The cover of the duvet is 100 per cent cotton, the filling is 100 per cent polyester, making for a lightweight duvet that still has a cloud-like pillowy-ness to it.

This Silentnight duvet is perfect for spring and autumn, or if you feel the cold and the thought of a 4.5 tog makes you shiver. It’s still very lightweight though, as it’s made from 100 per cent polyester. The soft-touch cover is also polyester, but designed to wick away any sweat to help you stay cool all night long.

Another great thing is that it’s hypoallergenic and can be machine washed at 40C to blast all germs and mites. We found it offers the perfect level of warmth on an April night – we didn’t overheat underneath it, but found it comfortable and cosy. If you love a big fluffy duvet, this isn’t it. But again, it’s remarkable value for money.
