advice on lightweight winter duvets

Generally, the lightest duvets are down, followed by down and feather. They should last longer than man-made, ten years or so.

When I buy a down duvet, I look for those that are made by ethical, cruelty free methods. 

Microfibre duvets are the lightest synthetic filled duvets and the filling would be the closest in feel to replicating natural down filling. The negative thing is they don’t regulate body heat. Some of the other types of synthetic filled duvet might be heavier, but they might regulate body heat better than microfibre.

Thank you!

Try going somewhere like Dunelm where they have a selection of duvet's and pillows, unpackaged and on display so as you can have a good look and feel of what you're buying.
