There are few things more cumbersome to carry around than a carseat. When you’ve got more than one child, several suitcases, and a diaper bag — and only two hands — things can get really stressful. The Air-Porter is a versatile strapping system that lets you attach your carseat (or golf clubs, or guitar, or portable crib, or other cumbersome items) to your rolling suitcase, making it infinitely easier to haul your gear from the parking garage to the gate. It works with pretty much any suitcase with wheels, leaving you with a hand free to corral your kid.
