How do you store your sleeping pad? Therm-a-rest states that they should be stored unrolled; however, I would want something that could be stored in my pack, quick to go. Anyone have any recommendations or suggestions? Should I go with a closed cell? Are they affected by heat/cold? I keep my pack in the car by day but it follows be inside at night. Actually I sleep with it by my bed because GF won't let me put it in the bed. Is that wrong? She says I have issues.

Thanks
