The Nix Hydration Starter Kit is the first-of-its-kind wearable hydration monitor designed to help you understand exactly when, what and how much to drink. Ideal for athletes, runners, cyclists, and fitness enthusiasts, this real-time workout tracker analyzes your sweat during workouts to deliver personalized insights on your hydration needs. The kit includes one rechargeable Nix Pod, four single-use Sweat Patches, a charging cable, and a quick start guide—everything you need to begin tracking from your first workout. Using sweat-powered technology, the Nix hydration tracker pairs with a single-use sweat patch and activates only after you connect to the Nix Solo app via Bluetooth and begin sweating, prompting real-time hydration notifications to your phone, smart watch, or cycling computer. It tells you precisely how much fluid you've lost and when to rehydrate, helping you improve training, performance, recovery, and endurance. Lightweight, comfortable, and built for all levels of fitness training, the Nix hydration patch system offers science-backed hydration data without the guesswork. Whether you're training for a marathon, cycling race, or working out at the gym, Nix helps you hydrate smarter and keep your running hydration a priority at all times. Use your personalized Nix data along with the calculators offered within the free Nix Solo app to help with preworkout hydration protocol and recovery insights. Nix will tell you which electrolyte brand (LMNT, Nuun, Maurten gel, Liquid IV, etc.) to include in your running vest, running belt, or cycling water bottle based on your personalized sweat composition data. Whether you're lacing up your running sneakers or heading to the trails with your mountain bike, add Nix to your pretraining protocol. This is a sports wearable, not a medical device.
