Pragathi Guruprasad's Must Haves: From a $10 Eyeliner to Perfume Oil

Guruprasad doesn't just qualify the Lululemon Everywhere Belt Bag ($38) as a travel essential but pretty much an everyday must. "If I am going out for a bunch of meetings, it's in my work bag. If I am actually going on a trip and flying somewhere, it's with me." Her essentials are always on hand with this belt bag, and it can fit everything she needs in its spacious compartments, including her lip balm, perfume, hand sanitizer, passport and IDs, wallet, and more. "I'll usually wear it as a crossbody or around my waist," she says.

It's made from a water-repellent fabric, and it's designed to stay put no matter how much you move. The bestselling belt bag comes in a ton of different colors and prints as well. You can read our in-depth review of the Everywhere Belt Bag here.

Pro Tip: Besides the 1L size, the belt bag also comes in a larger 2L size: the Everywhere Belt Bag Large ($48).
