At 9 lbs., the CYBEX Aton G is 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. With SensorSafe, you'll gain instant insight into your child's well-being-even when your eyes are on the road. Built into the chest clip of CYBEX car seats, the SensorSafe clip connects to a vehicle receiver which sends alerts about your child's safety, right to the mobile app on your phone. It's the kind of unparalleled safety technology you've come to expect from CYBEX.
