Ergobaby's newer stroller, the compact Metro ($299), is a must-have for anyone travelling. It's 20.8 inches by 16.9 inches by 9 inches, and you can fold it up with the push of a button on the handlebar. Stow it in the overhead cabin if you're flying, or leave it in the trunk of the car — there will be plenty of space leftover. And the seat itself is quite comfortable for baby.
