A totally organic energy block from ProBar. These chews are packed with electrolytes, B vitamins, and carbohydrates for immediate energy. For an extra boost, the Berry Blast flavor includes 20mg of caffeine per serving, which comes from natural yerba mate tea (other flavors are not caffeinated). Stash a pack of these in your running vest to ward off bonks on your way up the north fork of Big Pine Creek.
