I am generally a car/tent camper so weight and or bulk is not really an issue. I'm a medium sized lady who carries a lot of my weight around my hips and rear. I'm an almost solely side sleeper. What is a good bag/pad combo? I currently have a Teton Bridger (canvas 20F, if that matters) which seems to be quite a bit wider than many bags on the market, but maybe there is something a littleeee bigger? I have to sleep hugging a pillow/with one between my knees so we both need to fit in the bag! But also need some decent warm support underneath me, because my lower back and my shoulders do not like being on the ground. Thoughts? Experience? Yeah I know, I'll never be a backpacker.
