The airflow vents are honestly the selling point for me—no foggy, stuffy bubble even when it's fully zipped against the wind. It snaps on over the seat in under a minute and folds right into the storage pocket when the sun's out again.

Took this out in a sudden downpour and the ventilation kept the inside from fogging up completely, which was my biggest worry with a shield. It fits snugly over the Metro 3 and stows away easily in the basket when the sun comes back out.

The ventilation holes actually work—no foggy dome after a drizzly walk, and the little one stayed dry while it poured. It zips on quick, and it folds flat enough that I don't lose trunk space for groceries.
