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.

The hydration biosensor comes with a rechargeable pod (weights less than .5 ounces), a charging case, cord and 4 sweat patches.

Battery life lasts up to 36 hours.

You must be actively sweating in order for the device to gather data.

Shipping options available for Canada, APO/FPO, and US territories.

Don't take our word for it


Hydration data is a must-have because it’s the single metric with the highest impact on performance and it's different for each workout

As an endurance triathlete we often call hydration the fourth pillar - it is just as important as the physical training itself!

There’s no piece of information that is more useful for training, recovery and competition than the hydration data that Nix delivers.
