"The Go2 is a great tool I use to help my body maintain high output during hard workouts. It keeps my oxygen levels high which in turn keeps me ready to go the next day - speeding up recovery in-between workouts."

“As soon as I saw the GO² Device I understood the science behind it and recognized the performance benefits. I've experienced a notable performance increase in training - particularly at high altitude - and look forward to extreme-testing GO² on my upcoming K2 winter expedition in Dec 2019.”
