Keep your duvet at its sparkling best Whether or not you've spent a lot on your duvet, one thing's for sure; cleaning them is not part of the weekly wash. That's why we think every duvet should be wrapped up in one of these protectors. Teflon-coated to repel dust, oil & moisture, your duvet will stay clean. But that's not all. Unlike other duvet protectors, you'll still be able to fully benefit from your duvet filling; the treatment enables the material to stay fully breathable. The lightweight polycotton is so fine you'll barely know it's there. So you can snuggle into cuddly down or cooling cotton without hearing a rustling, crackling protector.
