The energy-to-weight ratio of a fuel is crucial when weight is a limiting factor. Like when you’re trying to put a person on the moon. Or get an endurance athlete to the finish line in record time.

Precision Fuel & Hydration Chew Bars deliver 60g of carbohydrate for just 68g of weight. They're like rocket fuel, but for human beings. 

The PF 60 Chew Bar can feel more satisfying to eat than gels during longer races and when working at slightly lower intensities. They’re a great way to mix up your fueling plan
