Jake Shane's Festival Packing List Is Surprisingly Practical

Celsius Sparkling Retro Vibe Functional Energy Drink ($3)

The days are long during festival season, so Shane turns to Celsius to keep the energy high. "We're running around all day and these help give me the energy I need to keep going throughout the festival," he says. Each can has 200 milligrams of caffeine, plus seven essential vitamins and zero sugar. His current flavor of choice is retro vibe (a mix of raspberry, orange, and lime).
