Downmat\Synmat 7 is 7cm thick, which is 2.8 inches Downmat\synmat 9 is 9cm thick, which is 3.5 inches The DLX versions are 6" wider and a few inches longer. As for pillows I'm still on the hunt for something a bit smaller packing. I went through a town, down is crap, if it compresses to the size of a shot glass then it will also do so with your head on it. I have I believe a Kelty luxury something and I picked up another from walmart which was the travellers pillow, it's a regular pillow thats been chopped in half. No, it doesn't pack that small, I put it in an old MC cover bag, which is something like 6x10x2. the pillow is simply folded in two and shoved in there, the Kelty fits into another one, same size, compresses better. Key is to not store them that way. Just like your sleeping bag or pad.
