I would try making one yourself. From experience, I know that a duvet cover made from heavy denim is very heavy to sleep under. Fill it with a cooler or warmer polyfill quilt, depending on weather, cuz polyfill is heavier tha down. Try it out! If more heavynrss desired, you could layer up what you put inside the duvet cover, such as those thin flannel mattress pads with rubber filling.
Denim is one of the things I'm sensitive to via touch.
I also can't really imagine polyfill being able to get to a 15+ lb blanket without it getting too warm.
