Question: what is the difference between microfiber and hollowfibre duvets?
Answer: Technically, the key difference is that micro fibres are much finer than hollow fibres giving a lighter, more luxurious feel. ... These differences in practice mean that microfibre duvets tend to be softer and give a bit more of a 'down' type of feel, whereas hollowfibre duvets are more springy and hold their shape.
