I was very skeptical about this being a mid-weight duvet when I pulled it out of the package because of how light weight it is.  I thought I would be cold under this duvet.  However, it warms up really nicely and I've been sleeping better since receiving it.  My husband prefers a lighter weight duvet and I prefer a warmer one because I get cold easily so this duvet is just right.  Not too hot for him and I'm very cozy.  The outer material is high quality as well.  I'd recommend!
