The Aeros inflatable backpacking pillow has changed the way thousands of people sleep in the backcountry or while traveling. Luxurious, lightweight and compact, it features a super soft brushed 50D polyester knit exterior and a silent, contoured TPU air bladder for support and comfort. Inflation, adjustment, and deflation takes seconds, thanks to our patent-pending multi-function mini valve. Plus, secure the pillow to your sleeping mat using our unique Pillow Lock system. Inflate pillow in just a couple of breaths and fine-tune it easily with the multi-functional valve. Brushed 50D polyester knit is very soft and comfortable. Curved internal baffles create contours that cradle your head. Scalloped bottom edge centers pillow around your shoulders whether you are sleeping on your back, side or upright in a chair. Synthetic fill between contact surface and TPU bladder increases airflow for additional comfort.
