Comfortably Stay 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 Stay 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.

Bought this at the start of the first heatwave and haven’t taken it off the bed since. It’s very light and just right for these hot nights we are having. Love it!

Found this to be just what we needed in the recent heat wave. Enough to feel like you’re covered but without the warmth of a higher tog rating.

A handy duvet for very warm weather

Handy duvet for warm weather. Deducted star as I get into a knot with it during the night! I suppose to be expected as it is so light. Far cooler than my 4.5tog one. Looks grand on bed even without cover so overall quite happy with it.

Lightweight and cool for hot summer nights, and helps you sleep with that extra bit of weight you just don't get from a sheet

Still hot bit disappointed

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Duvet is still very warm. It’s polyester filling and I always found that warm, however I thought with it being a 1 tog it would be cooler than it is. It’s more like a 3/4. However it’s very light and I’m ok with it at the moment. On super hot nights I’m switching to just an Egyptian cotton sheet over us so that we can sleep.
