I used my thermarest compressable pillow today and I love it! http://www.rei.com/product/719843/th...:referralID=NA
The fabric has 2 sides, one for cold and one for hot weather. It squeezes down fairly small and lofts back up quickly and stays firm-ish... I wouldn't want a different pillow for camping (so far). I have a medium and it fits well in the shelf of my WBBB when I am lounging.
Jim, I have one of those as well and love it. I did not realize the two different sides though. I am glad you mentioned that. I will have to pay attention to that next time I am out.
