Brookstone Self Inflating Pillow The pillow has a valve which you twistx and it slowly inflates. Once it is done, you close the valve off so the air won't escape. When you are done, you open up the valve, fold it in half and push down on the pillow so it will deflate and fit into the carrying case. You can remove the cover of the pillow, and wash it. Very convenient for travel, especially since the world is slowly opening again. Pickup only due to its price. If you want it shipped, please add $3.
