I think this is the one I got for my fiancée a couple years ago: https://jysk.de/schlafzimmer/bettdecken/gewichtsdecken/gewichts-bettdecke-7-kg-gjendetu
I don't know if you have Jysk wherever you're from, but it seems decent quality. You can put a duvet cover on the blanket, so you can pick and choose whichever material you're most comfortable with.
Can't comment on how fair the production is - hadn't done that research back then. But at least it's not off Amazon
