Extremely comfortable, lightweight and surprisingly compact, the full-size Aeros Ultralight Deluxe inflatable pillow is 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. Inflation, adjustment, and deflation takes seconds, thanks to our patent-pending multi-function mini valve. Plus you can secure the pillow to your sleeping mat using our unique Pillow Lock system.
