There are wide or rectangular bags that are much less confining than a mummy.
I've always used a liner in a sleeping bag which can be used by itself and is easy to wash (make them myself and they stay in place with velcro).
My Klymit pad has a "Klymit V Sheet" cover that acts as a bottom sheet (and pillow trapper) so I don't lie directly on the mattress. It is awesome.
