The pad does the job. The pack size is pleasantly small. Inflated it has a good size. Unfortunately, the filling but brings nothing. So you sleeping on a pure air cushion. Bas one notices especially when moving. Self-inflating therefore not entirely true. Since I sleep mostly on the side, the pillow surrounds my ear. This creates an unpleasant pressure on the ear. Sometimes, therefore, it hurts in the morning. The package is quite good. It included a small bag, a rubber band and a repair kit.
