I was looking for a cushion for use in a sleeping bag that is as small as possible. Therefore, this pillow is of size, perfect for me. The pillow should not inflate completely you. Actually, it's enough to inflate it to 40%, then it is for me the most convenient, because a depression for the head is formed and more slowly slips the head of pillows. Generally pillows inflated with air are more uncomfortable than normal pillow, that fact away the cushion is comfortable enough. The inflation and deflation of the air is very fast. At the beginning of the plastic smell something unpleasant. The removal of the coating to wash without any problems. The cushion corresponds to the figure.
