Unlock smarter hydration. The Nix Biosensor measures your sweat rate, electrolyte loss, and fluid loss in real time—so you can finally stop guessing. Paired with your workouts, it gives you the data you need to dial in your perfect custom mix based on your actual physiology, not averages. Whether you're racing, training, or just dialing in summer sweat sessions, Nix + Blank's Custom allows you to find out exactly what YOU need! The hydration biosensor comes with a rechargeable pod (weights less than .5 ounces), a charging case, cord and 4 sweat patches. 4x Sweat Patch Refills = $25 https://nixbiosensors.com/pages/nix-solo-individual-app#nixsolobiosensor
