I sleep hot year-round - winter, spring, fall, and especially summer. Waking up in a sweat is my norm, so heavy bedding is a no-go. That's why I love quilts. They're lightweight enough to keep me cool ...
A microfibre fill is always a little nicer than a hollowfibre filling as it tends to mean the polyester fibres are brushed more thinly for a light and airy feel, and the Emma Cloud Duvet does feel ...
I also get into what you should be looking for in a quality down comforter ... Even in the summer, when I have the A/C on, it never feels oppressive, thanks to how lightweight is.
