I sleep under two quilts and an electric blanket in the winter and under a quilt in the summer. (warm and natural batting) I am also in Southern California. It cools down at night normally with a couple nights of exceptions. We love our quilts here. My children sleep under multiple quilts in the winter or a fleece blanket and a quilt and in the summer just under the quilt. We also use them on the lawn and beach or as decoration.
