Active Cooling is about adding more cooling fuel, so your body can cool down better for longer periods. Just with water. Learn more in our website (link in bio).

🇩🇪 CHALLENGE ROTH, HERE WE COME! 🚴🔥❄️

We'll be at Challenge Roth from July 2–6 with a booth at the Expo Village!

Come find us and discover how our active cooling solutions help athletes stay cooler and perform better. 🧊💧

And because staying cool matters…

🍧 FREE SLUSHIES! 🍧

So don't wait too long — come by, say hi, and grab one before they're gone! 😎

See you in Roth!

Ready for summer? At Ultra Cool Tech, we have a packed season of new announcements, events, and collaborations with athletes and teams. All of them are connected by our purpose: helping athletes improve their thermoregulation through innovative active cooling solutions.

Stay tuned. More news is coming soon!

🏊‍♂️ BEATING THE HEAT IN THE WATER

Most athletes know that overheating affects performance. But did you know that cooling in the water is surprisingly difficult?

On land, your body relies heavily on evaporative cooling. Sweat absorbs heat and removes it as it evaporates. Underwater, that mechanism simply doesn't work.

Elite swimmers can generate 600–1,000+ watts of metabolic heat during high-intensity efforts. Only a fraction becomes propulsion. The rest becomes heat that must be removed.

In cool water, the body can usually dissipate that heat through conduction and convection. But in warmer water or when wearing a wetsuit, heat can accumulate faster than it can be shed. As core temperature rises, power output, technique, and comfort can all suffer.

To help address this challenge, phase-change materials (PCMs) provide an additional cooling pathway by absorbing excess heat through latent heat transfer.

This principle is at the core of the new EZ Hydro-Glide, developed through a collaboration between .co.uk and Ultra Cool Tech. Combining EZ Gains' expertise in performance-focused swimming solutions with Ultra Cool Tech's experience in sports thermoregulation, the teams worked together to develop a solution that helps swimmers manage heat in both warm and cold water environments.

From PCM formulation selection to heat absorption testing and hydrodynamic integration, every detail was designed to deliver meaningful cooling without adding bulk or disrupting performance. It also protects the head from impacts, keeping swimmers safe during the race.

Sometimes, improving performance is not just about producing more power.

It's about managing the heat that power creates.

Polish ultrarunner Tomasz Sobania is currently taking on an extreme challenge: running 50 marathons in 50 days across all 50 U.S. states. Now approaching the halfway point, the "Polish Forrest Gump" is facing extreme heat in several states, a challenge that requires the right active cooling solutions.

Tomasz chose our products to help improve his thermoregulation throughout this incredible journey across the United States. By combining the Glacier Hat and Glacier Towel with proper hydration, he is managing to endure the gruelling conditions on the road, especially in the southern states.

His journey is well worth following, offering valuable lessons in endurance, resilience, and the importance of choosing the right strategies to achieve ambitious goals. Running 50 marathons in 50 days across all 50 states is no small feat, and Tomasz continues to prove what is possible with determination, preparation, and the right support.
