CORE Body Temperature Monitoring

For high level and serious athletes

Improve your training and competitive performance with Core Body Temperature monitoring
Why Core Body Temperature?

Core body temperature is a vital sign of human health.

It is the temperature of inner organs, tissues and the brain (and it's different from skin temperature). Core body temperature is widely used to monitor the body in many fields.



CORE is based on innovative technology created in Switzerland and is used by experts worldwide

a new world of sport insights

Up to now, core body temperature could only be measured continuously using invasive methods like thermometers, probes and electronic pills or in controlled environments, such a lab or a hospital. 

CORE is the first wearable device that continuously and accurately measures the core body temperature on the go.

But I can already tell you that the riders are extremely interested in the measurement and we see really a big GAMECHANGE here if we are able to have the body temperature available all the time during trainings and races. 

'Mystery' World Tour team head coach

I have been implementing indoor training with professional cyclists for many years now. One of the significant aspects of this training is the time spent with an increased core body temperature. Now, to be able to monitor and assess this metric with CORE, our training will go to another level of advancement

Arm Strap

Regular price 12.95 CHF

CORE can be worn on the upper arm

CORE can be comfortably worn on the upper arm - accuracy may be affected

Many users find the convenience of wearing CORE on the arm strap over being worn on the chest an acceptable trade off for comfort over decreased accuracy.

NOTE: When CORE is worn on the arm accuracy is decreased.  This is due to the thermo-regulations differences between the chest and upper arm.

The CORE arm strap is made of a soft durable material suitable to be worn in harsh conditions such as sport and still comfortable enough to be worn all day. The simple Velcro adjustment system allows for the one size to fit most.

*CORE device is not included with the arm strap.

Chest Strap

Regular price 9.95 CHF

CORE worn on the chest is the most accurate location to monitor Core Body Temperature.  The chest strap offers a convenient reusable way to wear CORE for activities or extended wear.

CORE chest mounting strap

Many users find the chest strap more comfortable or convenient than the medical patches especially for extended use - though others find the opposite to be true.  So it ends up being a personal preference as the accuracy is equivalent with either solution.

The chest strap is made of soft stretchable nylon that can be easily cleaned and reused.  The simple clip adjustable system accommodates a wide range making for a one size to fits most.

 *CORE device is not included with the chest strap. 


Spare magnetic charging cable

CORE magnetic charging cable

To keep CORE waterproof we needed to find an alternative solution from a standard USB cable meaning it can be difficult to source a spare cable if needed.

We recommend a spare/replacement in case of damage or accidental loss.
Note: charge from a powered USB port.  CORE draws such a small current often battery pack chargers do not get activated with the small current draw.
