I absolutely love that this is cotton! Blended materials are okay but there's something about a 100% cotton duvet. I look forward to kicking off my shoes and getting into this duvet, it feels buttery soft and cozy. The best part is that the material gets better and better as you keep washing it, it truly softens with every wash. I use a huge mesh laundry bag to wash and dry this so my machine isn't too rough with it. The duvet doesn't get too hot, another plus!
