G2 thirst-quenching powder replaces what you sweat out with the same electrolyte-charged hydration of Original Gatorade Thirst Quencher, but with half the calories. Proven hydration with electrolytes, this powder in Glacier Freeze flavor is a good choice to fuel lighter practices and off-day training. Single-serve pouches offer convenient, on-the-go packaging. Simply tear open and mix with 20 oz. of water.
