Gatorade has always been a leader in hydration innovation. With the Gx Sweat Patch, they're going beyond electrolyte-infused sports drinks and teaching athletes how to properly fuel the body for optimal performance. The single-use device is worn on the inner part of the left arm to collect sweat as you workout. Once the activity is finished, users scan the patch to sync it with the GX app, where athletes will get a full sweat profile that includes sweat loss, sweat rate, and sodium concentration. The data will provide personalized hydration recommendations that can reduce the chance of cramping and dehydration and improve recovery time.
