ClearLux products meet federal car safety flammability standards without flame retardant chemical treatments. GREENGUARD Gold Certified, the KeyFit Max Zip ClearLux has been tested for low chemical emissions, contributing to healthier air quality around baby. Ideal for baby travel, the carry handle features easy, one-hand adjustment and two harness buckle pockets on the carrier keep the harness out of the way for a hassle-free experience getting your baby in and out of the car seat. The KeyFit Max Zip ClearLux offers more headrest height and legroom to maximize rear-facing use, featuring a 5-position, Easy-Extend Headrest System that raises with the harness to accommodate growth up to 32".

The baby car seat carrier clicks effortlessly into the included stay-in-car car seat base and compatible Chicco strollers creating a convenient car seat and stroller combo. Premium LATCH connectors and a SuperCinch force-multiplying tightener helps achieve a secure fit during installation with a fraction of the effort. One-hand ReclineSure spring-loaded leveling foot works in tandem with RideRight bubble levels to help verify and achieve proper car seat angle. The LockSure steel-reinforced belt system helps achieve a secure fit with the vehicle belt.
