The most common cause of air loss in Aeros Pillows is a puncture, a problem with the airproof barrier, or one of the RF welds. Moisture from condensed breath can cause issues with the welds or airproof barrier during longer-term storage, which is why we recommend storing your Aeros Pillow unrolled with the valve open. Repairing
Aeros Pillows can be challenging, so replacement may be your best option. If the pillow was purchased from an authorized Sea to Summit reseller, the replacement would be covered by the warranty. Therefore, we recommend contacting us to discuss the issue and explore replacement options.
