Familiarity: I've put it through the wringer
I have tried just about every hydration product out there and Skratch is the only one that has truly worked. As a high-altitude endurance athlete who sweats a lot and has a sensitive stomach, Skratch does not use any artificial preservatives or colors. Its all-natural flavors are very easy to digest, leaving me without any cramps for the first time. It has a prime ratio of electrolytes and enough calories to help optimize my performance during long 12+ hour days out climbing high mountains. I also instantly noticed my times improving by at least 5-8 minutes while out on long bike rides as well. I will not go back to anything else!
