- Reviewed in the United Kingdom on 8 June 2025Size Name: DoubleStyle Name: 4.5 TogVerified PurchaseGreat value feels so soft and a lot better than my old one very nice
- Reviewed in the United Kingdom on 9 May 2025Size Name: DoubleStyle Name: 4.5 TogVerified PurchaseI wanted a lighter duvet for Spring/Summer than my heavy and warm 10.5 tog winter duvet and this hits the sweet spot. It's cool enough for the average UK summer yet still manages to be cosy at the same time. You may want an even lighter duvet for those rare hot and balmy nights, but for Spring and most of the summer this one is ideal.

5.0 out of 5 stars Really Like It
Size Name: KingStyle Name: 4.5 TogVerified PurchaseMy wife and I sleep a bit hot. We were finding it difficult to find a duvet that was light, cool but still fluffy. We Tried a microfiber that was supposed to be all season, and two down duvets that were also supposed to be year-round. Each roasted us.
This duvet is warm without cooking us. The others seemed okay initially but within a relatively short time in the night had us cooking as they hold so much body heat in. This duvet does retain "some" heat but we are good with it.
