Some stroller brands known for their sleek designs and popularity among city parents include Uppababy, Baby Zen, and Mountain Buggy. They often feature lightweight frames, easy maneuverability, and customizable options. Though each has a range of models with varying price points, they can still be considered an investment piece. It's also good to keep in mind that some of these sports strollers might have compromises in terms of features or compatibility with other baby gear, so it's important to prioritize your needs.
