Wool duvet

[fruitcake]

Birds don't sweat.

Instead they have other 'mechanisms' to cool down, including stretching their wings to defeat the insulation and release body heat - which you probably can't do with your duvet, while you're sleeping. They also do something unspeakable involving certain bodily fluids on their legs - which you wouldn't want to do in your bed.

It's pretty much only primates that sweat. Other mammals do but only minimally.

Thinking about getting one.  Any thoughts on these? -

Not sure if there is much difference between brands, type of filling, etc

Horses famously sweat (while men perspire and ladies merely glow).

This is why horses have blankets not duvets.

Just got a Slumberland wool medium weight double for £45 from Amazon.  After a couple of nights I'm very impressed.  Warm without any of the sweating I used to get with feather & down.

I believe that women glow and men plunder...

Been using a wool doofer for ten years now, I love it.

Another couple of nights in and I'm really growing to like this thing.  This is usually the transition time of year when the lightweight is not warm enough and the winter one causes sweating.  None of that with this - just perfect!

Mrs Morat informed me that we were switching to a wool duvet a couple of years back. It's been fine for me. I like the weight when it's the right temp, but i find it a bit cold in the winter and I slept on top of it for most of the summer. But that's just me. (Devon Duvets, I'm told)

I've had a down duvet since I was a toddler & Mum imported cot-sized down duvets from Denmark.
I think I was still in a cot when I started school.
I think those who grow up with duvets get used to regulating heat by exposing & covering as needed.
My formerly blanket-using partner never seems to stay/get warm or cool enough and constantly complains about the duvet!
