Since I love everything efficient when it comes to travel, I need to mention Baubax, the swiss knife of jackets. It come with an inflatable neck pillow, a sleep mask, dedicated pockets for everything (phone, charger, passport, glasses, earbuds, tablets, keys, wallet), and additional features such as microfiber cleaning cloth or hand-warming pockets. Ah yes, and it's thermo-regulating. The ultimate functional jacket.
