Mockingbird Modular Single-To-Double Full Size Stroller 3.0 - Black Windowpane

The NEW 3.0 version of Mockingbird’s award-winning Single-to-Double Stroller is packed with premium features to make every stroll even more comfortable for your child and convenient for you.
The Single-to-Double 3.0 is the only stroller with built-in head-to-toe UPF 50+ protection. Mockingbird’s exclusive FullShade™ System combines an XL extendable canopy and a new LegShade™ to create maximum shade for your little one on sunny days, while ventilated mesh panels promote airflow to keep them comfortable. A reversible, seasonal seat liner flips from a cushioned everyday side to a breathable mesh side for cool comfort (and is machine-washable for easy cleaning).
Other new features of the Single-to-Double Stroller 3.0 include a quick-snap magnetic buckle to help with wiggly toddlers, reflective piping for safer nighttime strolls, extra pockets for both parent and child, and a height-adjustable canopy so you can keep strolling even as your child gets taller.
Your little one will enjoy smooth strolls thanks to all-wheel suspension and shock-absorbing tires that never go flat. And parents love the thoughtful details that just make using this stroller so convenient: Easy one-hand fold, a rotating handlebar to accommodate caregivers of different heights, no re-thread harness with one-hand strap adjustments, and a generous XL storage basket.
The Single-to-Double Stroller can be used from birth with Mockingbird’s cozy lie-flat Bassinet, the practical space-saving Infant Seat Insert, or the Car Seat Adapter that is compatible with over 40 infant car seats so you can build your own Travel System.
When your baby develops head and neck control (around 6 months), they can graduate to the stroller seat, which has 5 recline positions and is reversible, giving you lots of flexibility to adjust seating positions as their preferences evolve.
The stroller starts as a single, but if your family grows, you can expand it to a double by adding the 2nd Seat Kit. You can also accommodate three kids by adding the Riding Board attachment. All Mockingbird attachments can be swapped out in seconds without tools, so you can easily switch up configurations as often as you need to—think single mode with the Bassinet during the day, then double mode with the stroller seat and a car seat for errands in the afternoon.
With such impressive design, high quality materials, and a price that’s hundreds of dollars cheaper than most other premium strollers, it’s no surprise Mockingbird has rapidly become so famous in parenting circles and won countless awards like:
