I know the feeling of trying out a quilt and thinking, "this is going to be way to drafty." That is the first thought I had when I pulled my EE quilt out of the box. One key I found was snapping and cinching down on the neck. That pulled the quilt around me all the way down my sides to the foot box. Before cinching the neck it was in essence free flowing at the top and felt like a blanket that wasn't wide enough.

You definitely need enough material to tuck underneath you, so you don't get as much weight savings as you might think at first. But they do end up being lighter and less constricting than a normal sleeping bag.
