Train and perform at your absolute best with the most accurate non-invasive wearable device for continuous core body temperature monitoring.
The sensor allows you to easily see how much your core temperature rises with effort, so you can train your body to adapt to internal and external heat. You can also design personalized cooling protocols crucial to helping you sustain your power and pace on race day. With CORE, you’ll be ready to perform at your absolute best in any conditions.

Product Description
Please note, when CORE is worn on the arm, the accuracy of the core body temperature measurements is lower as the thermoregulation of the arm can different from the torso/chest.
When it is more convenient to use an arm strap and the level of accuracy from wearing CORE on the torso is not needed, the arm strap is made of a comfortable elastic material, perforated for improved breathability and with velcro for convenience and adjustability.
The black arm strap is 'one size fits all' (as it can be adjusted to fit) and is designed to remain comfortable for sports and all-day use.
This includes ONLY the arm strap and the CORE device is not included and is shown in the photos for demonstration.
