This is the bane of my touring existence. I love sleeping with a pillow, but I don't have room to bring my favorite. I have gotten by with stuffing my sleeping bag stuff sack with all the spare clothes I had, then putting a towel or folded fleece vest over that. It's not that comfortable, when I toss and turn in my sleep I destroy the careful arrangement and wake up with a sore neck, plus, it takes pretty much all of my clothes to fill up that bag! I bought a backpackers pillow once, but it was so small and compressible that when I put my big head on it it squashed down to the thickness of an envelope!
I'm thinking about using a smaller bag than my sleeping bag stuff sack, so it won't take as many clothes to make a suitably thick pillow. Hmm.
I'm wondering about inflatable pillows. Does anyone have any good reports on one? I saw Thermarest pillows advertised, but it didn't appear that they are inflatable. If they're compressible enough to squish down to fit in my panniers, they're probably too compressible to hold my head up where I want it. I thought a self-inflating Thermarest pillow, like their mattresses, would be a good thing.
Anyone have any tips? Recommendations?
