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. Features: Inflate pillow in just a couple of breaths and fine-tune it easily with the multi-functional valve. Stretch-knit 20D polyester knit is very soft and comfortable. High-strength TPU air bladder is soft, silent and supportive. RF welded for strength and durability.
