Sweat Patch Refills

I do like this however, I think 4 patches for 25.00 is expensive. I like seeing how much I sweat during runs, hot walks and weight training. With these single use it’s expensive. I wish they could be used once a day for all workouts

Great overall, but having to run the phone app at the same time is inconvenient

They work great especially on my long run or bike workouts for long duration help me keep on top of my hydration.
