I wanted to like the Montbell pillow, but I recently tried it and found that inflatable pillows just don't work for me. The air inside causes my head to bounce too much, which is why I needed a pillow in the first place to use with my Big Agnes Air core mattress.
Down is in my opinion the best material for a pillow. This is what I use at home.
I recently got the Western Mountaineering Cloudrest, and let me tell you–that is 4.3 ounces of pure comfort well worth it. It even comes with its own stuff sack! Last year I carried a large down pillow that weighed 8.5(!) ounces, so this was a significant weight savings for me. Since I am lightweight, not SUL, I find the down pillow justified to get a good night's rest.
