I have a memory foam travel pillow by thermarest which packs down into a cyclinder the size of a jet boil. I also have a thermarest dry/stuff bag which can be tuned inside out and has a fleece cover! Does the job stuffed with a fleece jacket. And lastly I bought a small pillow off tengu at the Bushmoot sale stall which is a mix of foam and inflation. It rolls up pretty small. I've found that the combination of the foam pillow and the inflatable pillow are like heaven - as between them they are very adjustable in terms of height and bungyness. I'm a happy side sleeper and these plus a thermarest and a golite quilt inside a borah gear bivi, with an extra down blanket by Yeti means I am happy and toasty and most importantly ASLEEP through the night. Oh and ear plugs. When I am camping, these take up most of the space in my rucsac. And oh boy I may be smelly and grubby (cos of few clothes and not much wash gear) but I sleep really well, so I'm never grumpy! I'm sure smelly and grubby were in the original cast of Snow White, but they didn't make the director's cut.
