If you love all things organisation, you probably already know about Dagne Dover. The brand is praised for its functional bags of all shapes and sizes. If you travel regularly, on top of heading straight to work after the gym, the Landon Carryall ($155) is a smart buy. The bag, which features a shoe duster and a water bottle pocket, slips right over the handle of a suitcase for easing strolling in the airport.
