I have used the exped air pillow (size small) for a while now, but I get annoyed with the curved section and the thicker section. The thicker section would nest perfectly under my neck when I am laying on my, except for the curved cutout section which pushes against my shoulders and moves the thicker section more under the back of my head instead of supporting my neck. It works fine when sleeping on my side though, since my shoulder fits nicely into the curved cutout section.
I have been considering replacing my exped with a Snoring Cub pillow from Arrowhead Equipment. http://www.arrowhead-equipment.com/arrowhead-originals.html
3oz, 3 inches of climashield loft, 5" x 9"
They also make a Snoring Bear pillow that is 8" x 12", 5 inches of climashield loft, and weighs 5oz.
