The new Cybex Aton G Infant Car Seat weighs in at just 9 lbs. Itis one of the lightest infant car seats on the market. The Aton G takes safety and comfort seriously with the use of linear side-impact protection, which reduces collision forces in a side impact crash, in-shell air ventilation for natural airflow and a UPF50+ sun canopy. Additionally, the SAFELOCK belt tensioner provides a quick and easy installation.
