World’s Most Convenient Palm Cooling Device

Palm cooling is a breakthrough in performance and recovery, and Kühler is the easiest, fastest, smallest, and lightest palm cooling device ever made.

And it works.

When you exercise, your body rapidly produces heat
Heat accumulates much faster than it is released
Once the body overheats, performance drops
- Nervous system shuts down
- Muscles fatigue faster
- Cognition slows

Palm cooling has been validated in 30+ research studies
Patented cooling technology to accelerate heat transfer
Immediate recovery and performance enhancement
- 28% increase in repetitions in just 2 minutes
- 25% lower rise in core temperature

Recovery: Heat stress is a primary cause of fatigue. By rapidly removing excess heat, the nervous system and muscles quickly recharge, providing real-time recovery.
Endurance: Increase physiological capacity to do work by improving capability to compensate for the accumulation of metabolic heat production.
Performance: Reducing heat stress provides a competitive advantage over others: break through plateaus and be the difference between winning and losing.
Cognition: Heat stress reduces cerebral blood flow and acts as a cognitive load. By removing excess heat, cognitive performance increases.
Heat Stress & Safety: Proactive cooling slows down the accumulation of heat and lowers the risk of heat stress and heat-related incidents. Prevention > Reaction.

Who:
- Athletes to optimize performance
- Strength Coaches to optimize training sessions
- Athletic Trainers to mitigate the risk of heat illness
- Biohackers to augment exercise, recovery, and sleep
When:
- During timeouts, halftime, dugout/bench/sidelines
- During rest breaks between sets and sprints
- After training with elevated core temp
- Before bed to pre-cool before sleep
How:
- Grab Kühler, pull trigger, hold for 30+ seconds
- Two hands is ideal, one is sufficient
- Repeat as needed and able
