Add the Peg Perego Primo Viaggio 4/35 Infant Car Seat to your Agio Z4 Stroller for the ultimate travel system.  
Allows the Agio Z3 Stroller to be compatible with Nuna Pipa, Maxi Cosi Mico,, Cybex Aton, and Clek Liing series infant seats.

Better yet, select the Agio Nido and no need for any adaptors and have a Made in Italy infant seat that has a load leg and anti-rebound bar.
