Comfortably Cool 1 Tog Duvet

Product code: T350009D

This lightweight summer duvet features innovative Cool Comfort™ technology to regulate your temperature during warmer nights. The pure cotton cover improves breathability, creating a naturally cooling sleep environment. Part of the Comfortably Cool range, it offers the perfect balance of comfort and temperature control for restful summer slumber.

The tog rating refers to the effectiveness of the duvet to retain heat – the higher the tog, the warmer you will be when you're snuggled beneath it. A 1 Tog duvet is perfect for the summer months when the weather is at it's hottest.

Great summer duvet.

Perfect duvet for summer nights. Lightweight but feels like having a duvet on you rather than a sheet.

This is perfect for UK hot summer nights. Gives substance to just a duvet cover so it keeps in place rather than twisting around. Very pleased with it.

Worthwhile buy

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I debated buying this and what swung me was that I like something covering me when I sleep, and if it's just a sheet I tend to end up tangled up in it. 4.5 togs is just too hot in a heatwave, and this is perfect: weighty enough to stay put but light enough to mean I stay cool. With the more typical summer weather I may return to the thicker tog as needed, but this is really helpful for sleeping on those nights that would otherwise be a waking discomfort.

Purchased to get away from the awful overnight heat under a too heavy 'summer weight' duvet. It's absolutely right and the most comfortable we've been in years. An excellent purchase.

Good but not perfect

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

This was bought recently to replace the Supremly washable 1tog duvet i bought last year( almost impossible to get into a cover due to polyester outer). This had a cotton cover and glides in smoothly. It matches the length of my m and s duvet covers ( hurrah!!) but it is noticeably warmer than last year's. Still comfortable but not quite as thin or cool. May take to using the supremely washable one without a cover on very warm nights.

I got this for our motorhome and its just what I wanted. Soft and light and very comfortable. I'm probably going to buy one for home too, it will be great for the summer months. Its great that it has a cotton cover.

Perfect for hot summer weather

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Ideal for hot summer nights, nice and cool, breathable thanks to the cotton outer, it is nice and light weight so provides the comfort of something more than a sheet but doesn’t feel oppressive or heat-holding. Good quality materials and stitching. Looks like it would be very easy to launder (even this super king size).

The duvet is heavier than my 2.5 tog and as warm as my 2.5 tog so disappointed. I was expected lighter and a better overall duvet

We required a lighter duvet for Summer months - so far fits the bill.

When you are too hot all the time!

Yes, I recommend this

For the over heated person in your life! In the middle of winter they sleep with a 4tog and the window wide open, hopefully this will at least keep the window closed 😁

just what I was looking for. I hate polyester covers on duvet. The static when changing sheets is horrible! There are no many companies who do 100% polyester outer and 100% polyester inner.
