From Nuna, this flex system features: Did your favorite car seat just sprout wheels? Well, sort of. It's called meeting the moment. This all-in-one PIPA urbn flex system gets that parenting demands flexibility, and your gear needs to keep pace with the pivots. So it flexes with your day, transforming from a car seat to a stroller so you can go from parked to pushing and back again in seconds. Secure and seamless, the car seat latch system installs without a base or a trace. With carbon fiber strength and showroom-worthy style, the featherlight frame folds in a flash and looks anything but basic. Best of all, it's built for years, not just months. No tricks. No trade-offs. Because smart parents want smart systems, not shortcuts or clunky compromises.
