Both the UPPAbaby Vista V2 and Mockingbird double stroller have a pretty standard size canopy (before any extensions). Both also have a covered mesh peek-a-boo window that also can help airflow.
Both the Vista V2 and Mockingbird canopies are expandable for extra coverage.
Above shows a side-by-side of the UPPAbaby Vista V2 vs. Mockingbird double stroller’s extended canopies – at first glance, it looks like the UPPAbaby Vista V2 has better coverage, but the Mockingbird seat is reclined. When you look at the canopy coverage of the Mockingbird when upright, it has similar coverage to the UPPAbaby Vista V2.
One thing to note is that Mockingbird also comes with a removable magnetic sunshade that can attach to the canopy to provide additional coverage.
Also important to us is that both canopies offer UPF 50 / UV Protection.
Winner: Tied We’ll call this one tied, though Mockingbird does have a slight edge if you factor in the removable magnetic sunshade. Personal preference will factor in to whether or not someone will find the magnetic sunshade useful.
