One4Life takes your child from birth to big kid with Britax USA safety and click tight installation. It easily converts from rear-facing infant car seat, to forward-facing 5-point harness, to high-back belt-positioning booster. The Cool N Dry fabric improves air flow for a cooler ride. Made with 30% bamboo charcoal, it wicks away moisture to help keep your child dry. Click tight is as easy as buckling a seat belt, so you can install with confidence, every time. Color-coded belt paths show you where to route the seat belt for each installation mode. Plus, easy-read indicators help you find the correct recline angle. A high strength steel frame, Crumple zone, and V-shaped tether help absorb crash energy. And, 2 layers of side impact protection surround your child's head, neck and torso. As your baby grows, adjust the 15-position headrest & harness in seconds To create the perfect fit. When it's time for the booster mode, simply tuck the harness into the built-in storage compartment.
