When the temperature rises in the Summer months it is tough for me to sleep in a sleeping bag. Typically I use quilts with my hammock so sleeping on the ground with a comfortable pad and top quilt is the way to go. I have used this combo several times with a lightweight shelter. The Proton Blanket is also a great item to keep in the car in case of emergency or using around camp.
