So you’re about to hop on a plane/ferry/train/bus/bicycle for some summer fun. What are you bringing along to look and feel your best? We polled W editors for their summer travel beauty essentials—the products that keep faces, bodies and hair refreshed and hydrated after days spent hiking, swimming, basking in the sun, getting sweaty on the tennis court or on transatlantic flights—bonus points if they come in TSA-approved packaging. From luxe mineral SPF to the magnetic cases that make all of your favorite creams and gels into perfect travel-sized minis, these are the holy grail items we have in our bags this season.
