In the summer months, it's common practice to switch to a lighter tog for a comfortable night's sleep. There are plenty on the market to choose from, and generally lighter tog duvets are cheaper than heavier winter ones, so there's no need to splurge.

This best-selling M&S number has been getting high praise from shoppers, with one saying it's 'perfect for hot nights' - just what you need when the warm weather decides to arrive (and stick around). The Comfortably Cool 1 Tog Duvet, comes in double, king and superking sizes with prices from £45.

The single size has currently sold out online, it costs £35. The description reads: " Warmer nights will never be stuffy with this super lightweight summer duvet. Gentle and comfy, our 1 tog duvet is our lightest weight duvet offers the perfect way to stay fresh and cool during the warm summer nights.

"With a pure cotton cover for a soft touch and clever Climate Control technology, this light duvet regulates your temperature as you sleep, keeping you cool and comfortable all night long. This duvet is a great addition to your bedroom, and is designed to wick away moisture from the body, ensuring you’ll always wake feeling refreshed."

The lightweight duvet is one of the retailer's most popular, with more than 470 reviews and a 5-star customer rating. One fan wrote: "Perfect for hot nights. Would definitely recommend."

A second commented: " This duvet is a game changer for me. I’m a woman of a certain age who has been battling night sweats for a while now. I bought the bedding which definitely helped but having this duvet as well has enabled me to have a full, uninterrupted night's sleep for the first time in a year. Thank you M&S!

"The duvet is just the right weight to not get tangled up like a sheet but heavy enough to provide comfort and light enough to not cause overheating. When it first arrived I thought it would be too thin to fit correctly in the duvet cover, but the fit is perfectly fine, although I have only used the duvet with the comfortably cool duvet cover."

And a third said: "Brilliantly cool! This 1tog duvet is lovely, it does keep me nice and cool. Have the cool duvet cover too."

One customer said that they found the duvet hot to sleep in, despite its lighter weight. They wrote: "This duvet is supposed to be “comfortably cool”, it really isn’t. It’s only 1 tog but is far too hot. I definitely would not recommend this duvet. It is very overpriced for what it is."

Another shopper said they feel that the stitching will unravel over time, explaining: "Duvet finishing poor done with over stitching which looks as if will unravel over time."

Over on Amazon, this Silentnight Summer Breeze duvet is 2.5 tog. With prices from £18 for a single, it is described as 'perfect for over-heaters and cool comfort seekers'.

Elsewhere, Dunelm has a Fogarty Cool Cotton 1 Tog Summer Duvet from £20. The retailer describes it as ' perfect for those summer months and has been made with a high quality and durable cotton cover and a cooling polyester filling for that right amount of cosiness.'
