The double version of our compact, superlight and convenient double stroller. This convenient side-by-side twin stroller is not only compact and superlight, but also will fit through the standard door with ease. Keeping two happy is simple with the individual adjustable hoods with a loop to hang their favorite toy, individual reclining backrests and individual child trays. This stroller is ideal for twins or two of different ages. The 60-40 baby stroller gives you versatility of using a Primo Viaggio SIP 30-30 car seat (sold separately) for an infant in the 60 seat while placing the older child in the 40 seat. As the baby grows out of the car seat, the 60 seat can be used for the older child and the 40 seat for the younger child. Both children can view the world ahead.
