Tailwind mixes with water to meet all your calorie, hydration, and electrolyte needs, without upsetting your stomach or making your taste buds revolt. Just toss it in a bottle or hydration pack, shake, and GO! The Naked flavor is a neutral base, not quite tasteless, but not overpowering like some flavors at full strength can be. Berry is surprisingly berry-like, as is the orange. I prefer to mix at half strength for long endurance events.
