Recommended for workouts of 45 minutes or longer, our lightweight durable hydration monitor quantifies when, what, and how much to drink (water or electrolytes) while analyzing your sweat moment-to-moment. The rechargeable pod clips onto a single-use sweat patch before the start of each workout to read and transmit data to the Nix app. It integrates with your smartphone or watch to deliver personal hydration data in real time providing hydration intelligence to improve your athletic performance, safety, and wellbeing.
Nix Sweat Patch Refills include four single-use sweat patches to be used in conjunction with the reusable Pod before each new workout. The Sweat Patch sticks to the bicep via adhesive and is completely non-invasive. We recommend wearing a patch during a sweat inducing workout, ideally running or cycling, lasting at least 45 minutes in duration. After your run or ride is complete, a post-workout summary in the Nix App provides intel that can help inform your hydration strategy going forward.
