I have had a down/feather duvet on my bed for years. The previous one was made in channels so the filling kept shifting to one end and some of the filling had escaped so it was not as warm as it was initially.
My new Wayfair duvet is Canadian made. I shop Canadian whenever possible, so this is important to me. The new duvet is sewn in pockets so the down does not notably shift and it the filling is completely down, so it is warmer and a little lighter than the previous one .
