In short

Hollowfibre is a synthetic fill used in duvets and pillows. The polyester fibres have hollow cores that trap air for warmth. Hollowfibre duvets are usually easier to wash at home than down and feather ones. Choose warmth by TOG rating first, then pick the fill. Fill power applies to down, not hollowfibre.

Microfibre is a finer synthetic fill that can feel softer, closer to down.

Check the wash label and your machine size before you buy a large duvet.
