I highly recommend big agnus park series bags. I also sleep on my stomach or side. They have a pocket sewn into the bottom to hold your pad. So its always in the right spot and not sliding out. It has a pocket for your pillow so your not chasing it at night. The cold weather ones have a hood for the cold. You can buy them in down or synthetic what ever your choice. They also sell a wedge to zip in if you find it alittle tight. I can honestly say i sleep as good in it as i do by bed at home.
