One bag, three jobs: airline carry-on, car seat, and cosy den. The Dupree II is airline-compliant hand luggage and an impact-tested car seat in one soft-sided carrier (do check your airline's size and weight limits before you fly). A structured base holds its shape and spreads the weight so it won't sag, mesh panels run the whole way around for airflow and a view, and the doors roll down and hold open with magnets for easy in-and-out.

Steel-reinforced ISOFIX latches lock it into the car in seconds, the flexible frame slides under a plane seat, and a trolley sleeve lets it ride on your suitcase. It comes with a leash, a leash storage bag, and neat extras like a luggage tag and a tracking-device holder.
