i think im going to get it because of its size and the reviews of read on it. i am a side sleeper.

i am also considering this pillow but will go with the first one listed unless i hear a good argument(other than it will fit with my GOGO).

I have the Exped pillow and like it. To save weight, I sometimes just use an inflated 3 liter size Nalgene Cantene which I already carry for water. Sleeping on my back, I don't notice much difference between the two.
