01
Capacity gets tied up
Additional thermal load ties up energy you need for performance.
WHY IT WORKS
Perform better.
Recover faster.
Sustain progress.
There is more in you than you might think. But under long or intense efforts, heat builds into a strain of its own — tying up capacity your body needs for performance, recovery and training stimuli that drive progress.

HEAT STRAIN
The hidden load that makes your body pull back.
Every rep, sprint or climb creates more than force — it creates heat. A lot of heat. Around 80% of the energy your body produces is released as thermal energy.
As effort gets longer or more intense, heat keeps building. Your cardiovascular system has to work harder, and your body spends capacity trying to regulate temperature — capacity you need to perform, recover and create the training stimuli that drive progress.
When muscle and core temperature rise too far, your body protects itself. Heat-sensitive enzymes involved in energy metabolism lose efficiency, muscles fatigue or fail, and performance drops — not because you are out of potential, but because your system is trying to prevent more heat production. CoolMitt® supports targeted heat release and helps reduce thermal load before it limits you.
THE SHIFT
02
Protective regulation kicks in
Your system reduces output before thermal load gets too high.
03
Capacity gets freed up
CoolMitt® reduces your additional thermal load — freeing up more capacity for performance and recovery.
BEHIND THE EFFECT
Why the
palm?
Your palms are not a random cooling surface. They contain specialized blood vessels, called arteriovenous anastomoses, which play an important role in your body’s natural thermoregulation.
Think of it as a thermal relief valve.
CoolMitt® uses this natural access point to help release excess heat in a controlled way. This allows your body to reduce thermal load more efficiently — and keep more capacity available for performance, recovery and sustainable training stimuli.
THE VISUAL PROOF
Heat transfer
made visible.
Thermography shows how quickly CoolMitt® works: after just 30 seconds, cooling becomes visible and noticeable. Your system is relieved from within — helping you stay fresher, return faster and regain access to your full capacity when it matters.
WHAT IT UNLOCKS
More capacity.
More access.
More of you.
CoolMitt® reduces additional thermal load and creates available capacity — helping you keep access to your full potential for longer.
More high-quality repetitions
More consistent sprint and interval performance
Faster recovery between efforts
Less heat-related performance drop-off
Sustainable training stimuli
Stay capable when others fade — and create stimuli that make real progress possible.
PERFORMANCE IN ACTION
For the moment
when the next set,
sprint, or shot matters.
When heat slows others down, you take capacity back — for more control, more freshness and more access to your performance when it matters.
SCIENCE BACKED PERFORMANCE
Small differences.
Big impact.
In performance-defining moments, it is often not large gaps but small differences that change the outcome. This is exactly where thermal load becomes relevant: when your body has to spend additional capacity on cooling, that reserve can be exactly what is missing.
In a randomized placebo-controlled clinical trial on repeated sprint ability, the group using CoolMitt® Palm Cooling showed, among other outcomes, less decline in sprint times, a lower heart rate after exertion and reduced muscle soreness 48 hours after testing compared with the control group.
According to the study, a difference of around 0.8% in sprint speed can determine who gains possession of the ball in a 20-meter sprint.

WHEN TO USE IT
Use CoolMitt® before heat defines your limit.
Before, during, and after intense efforts, CoolMitt® supports your body’s heat release — helping your system reduce additional thermal load and maintain access to maximum performance for longer.
01
BEFORE
Create thermal headroom before activity for more intensity and endurance.
02
DURING
Use breaks between sets, rounds, or intervals to reduce additional thermal load.
03
AFTER
Support recovery and help your system return to balance.
