Infant travel systems make traveling with baby so much easier: when you can click your infant car seat into a base in your car or snap it onto your stroller, it spares so much finagling. And who wants to undo a bunch of car seat straps and wake a peacefully napping baby up to transfer her from the car to the stroller? Nobody, that's who. Enjoy the ease of a travel system, the awesome all-terrain capability of BOB, and the supreme safety and comfort of Peg Perego with the BOB Trailers Duallie SE Infant Car Seat Adapter! It takes literally seconds to click this adapter onto your BOB Duallie SE Double Stroller, enabling you to securely snap your infant car seat on and go. Plus, a snack tray is included for your older child to enjoy. The BOB Trailers Duallie SE Infant Car Seat Adapter works with the Peg Perego Primo Viaggio SIP and Primo Viaggio SIP 30/30 infant car seats. Jogging with the infant car seat attached is not recommended.
