Warm but lightweight.  Perfect for all seasons.  Make sure to get a nice duvet cover to protect this comforter.  I love this!  It's soft and fluffy, no feathers have poked through.  Very well made.  The only flaw is that it didn't have tabs to tie onto a duvet, but that was an easy fix so I won't remove any stars for that, because most down comforters do not have them.
