Traveling with your baby can be a breeze. The new YoYo stroller from French company Babyzen ($399) is a boon for parents on the move (and downright revolutionary for anyone who’s ever attempted to collapse his stroller at security check with a kid in one arm and luggage in the other). Beautifully and cleverly designed to be steered, opened, and collapsed with one hand, the YoYo is lightweight: just 12.8 pounds. But its greatest advantage for frequent travelers? Not only is it narrow enough to be wheeled down the airplane aisle, it’s the only stroller that, when collapsed, meets airline carry-on regulations and can be stowed in the overhead bin.
