Tailwind Endurance Fuel
Model: Endurance Fuel
Chewing food is overrated, especially for those who have trouble digesting solids under exertion. That’s what our tester concluded after adding this high-calorie energy powder with electrolytes to her water on 10- to 12-hour dayhikes. “It works great if you’re moving fast and don’t want to fuss with real food,” she says. Unlike most hydration powders, Tailwind contains 100 calories per serving, so you’re cutting food weight without cutting fuel. It comes in caffeinated, non-caffeinated, and flavorless versions, but we like the mild raspberry. $2.25; 1.9 oz.
