I've tried regular camp pillows and I just can't elevate my head enough to be comfortable.
That's why I finally bought a small down pillow with extra stuffing. Feels exactly like the pillow on my bed....because it is. And it adds very negligible size to the compression sack that holds my sleeping bag.
