Extremely comfortable, lightweight and surprisingly compact, the full-size Aeros Ultralight Deluxe inflatable pillow uses a construction inspired by the Air Sprung Cells of our sleeping mats. It features a super soft 20D stretch-knit polyester exterior and a silent, TPU air bladder for support and comfort. We have updated the bestselling Aeros Ultralight Deluxe Pillow for 2019 to add compatibility with our unique Pillow Lock system.
