Bought the Red Exped pillow from REI the other day and returned it the next day. It is not very comfortable for the price. It packs very small and elevates your head from the ground but it was not worth it too me. I exchanged it for the Aeros medium size and it is much more comfortable. It is softer and it keeps your head off the ground and it packs up to about the size of a soup can. I'd recommend the Aeros.
