I was sent the Gx Sweat Patch, Water Bottle, and Pods for free from Influenster and Gatorade for my honest opinion. My husband used the sweat patch on one of this runs this week. The idea of the patch is promising but it needs some improvement before it’s worth the price tag… at least we think. He said it was weird running with the patch on. Also, the dye from the patch leaked all over his arm as you can see. It looks like a bruise. Once he took the patch off, the adhesive stayed behind on his arm. You scan the patch into the Gx app and it tells you your fluid loss, sweat rate, and sodium loss. It then tells you a recovery plan based off of if you want to recover, maintain, increase, or compete with your workouts. That aspect is pretty neat, but not worth it for the price tag and quality. Neat idea… fun to try out.
