Why would you pay for every workout?
The burden of sweat patches
While disposable patches for hydration monitoring can seem convenient, they may prove costly in the long run, especially for regular athletes. For those who work out three times a week, the recurring cost of disposable patches, ranging from $5 to $12 each, quickly adds up. This continuous spending, month after month, year after year, can detract from the focus on what truly matters – achieving your peak performance.

Why we do not use disposable patches?
Exercising three times per week adds up a total of 144 workouts per year.At a $5 per sweat patch the costs add up.
- Sticky on the skin
- Harder to set up
- Hairy bodies having problems
- Failed patch, lost $5
- Innacurate data
Now, there is a smarter choice.

It is been awesome being able to track hydration on my players. Some of them struggle with heat, and being able to benchmark them helped us buy the appropriate supplements.

This device has the potential to become the next hydration gold standard. It can detect when I start sweating, how fluid affects my body, and track my skin temperature during my training.
