NO they don’t!
Even ones which sound like they may actually be a natural fabrication - such as this one! - and the summer weight range they did (forget name), are all sadly still 100% polyester…!
After several years of evangelism about the range on here, many moons ago I succumbed…
Well I hated it every bit as I feared I might!
I did find it sweaty and static and fluffy!
I can just about cope with a poly-cotton mix in bedding but for me if I can afford it, it’s got to be cotton and ideally sateen! (Some bargains to be had on eBay!)
Sorry you seem to have triggered a Cozee home rant!!
To be fair, I’ve got a CH throw - double thickness - which must be 10+ years old and which I adore.
The texture is so silken and a lovely weight just wouldn’t want to sleep directly under it…
