Temperature warning

When you exercise, your body overheats and performance rapidly declines.

Every Athlete’s Kryptonite
Elevated core temperature is one of the most significant limiters of athletic performance: physical and cognitive. Core body temperature rises quickly, meanwhile heat dissipation is slow, delayed, and inefficient.
The World’s First Handheld Human Heat Sink
The patented KühlerTM device maximizes core temperature cooling.
No ice, no water, no effort.

Case study

Kühler was used for just 6 minutes (three rest periods) during push-up workouts: 10 sets to failure; two minutes rest.



Kuhler Technologies’ mission is to increase human performance capacity by developing effective, effortless, and portable personal cooling technology.


From fighter pilots to athletes to Ph.D. scientists, Kuhler Technologies is operated by mission-driven competitors who are obsessed with excellence.
