As elite athletes prepare for the most demanding moments of the winter sports season, adidas has unveiled its revolutionary CLIMAWARM SYSTEM. At the core of this next-generation pre-warming technology is Clim8® active thermoregulation. Discover how this collaboration supports adidas’ approach to elite athlete preparation in extreme cold.
Solving the “Pre-Race Window” Challenge
For elite competitors, the minutes leading up to the starting line are critical. This “pre-race window” is where muscles, despite a thorough warm-up, rapidly lose heat due to static waiting periods in sub-zero conditions. This cooling directly impacts peak power output and explosive performance.
The CLIMAWARM SYSTEM, comprising a high-performance jacket and trousers, is specifically engineered to solve this challenge by keeping muscles primed and maintaining peak power during these crucial moments.
“This collaboration with adidas is the result of a deep technical synergy between our teams. At Clim8®, we believe that the future of performance lies in the seamless integration of biology and technology. We worked hand-in-hand with adidas’ innovators and world-class athletes. Complex thermophysiology was successfully translated into an autonomous system. The result? Competitors stay focused and primed. We are incredibly proud of the collective engineering effort. It’s now time to bring this breakthrough to the starting signal.”, Julien Guéritée, Clim8 co-founder and Chief Product Officer
A High-Performance Technical Collaboration
The innovation is the result of a deep collaboration between adidas and Clim8®, informed by elite winter sport programs and extensive feedback from athletes in disciplines such as cross-country skiing, bobsleigh, and skeleton.
The integration of Clim8® technology transforms the garment into a precision tool for competition:
Integrated Technology: Ultra-thin Clim8® smart heating pads are fused directly into the garment and strategically placed over major motor muscle groups to drastically reduce heat loss.
Smart Thermoregulation by Clim8®: The system integrates our advanced intelligence, featuring “Eco” and “Boost” modes that allow the garment to become fully autonomous by responding in real-time to both the wearer’s movement and ambient conditions.
Targeted Assistance & Safety: Our technology provides precision warmth to the most vital areas of the body when needed most. Simultaneously, a built-in Clim8® safety mechanism prevents overheating, ensuring the athlete stays in the optimal comfort zone without excess sweat.

Success born from a shared vision
The CLIMAWARM SYSTEM is the result of intensive co-creation, combining adidas’ textile expertise with Clim8® ‘s technological know-how. By joining forces, the two teams succeeded in transforming a complex vision into a concrete solution for the field, proving that collaboration is the key to pushing the limits of human performance. This partnership perfectly illustrates how technological innovation, when applied to high-level sport, can overcome the most extreme environmental obstacles.
“The CLIMAWARM SYSTEM is designed to address a simple, yet complex challenge faced by athletes at the start line: how to maintain muscle temperature generated during the active warm up and stay powerful in the cold. We know that it’s in the pre-race window, during the gap between active warm up and the competition’s start, where heat is lost, but it’s also where power retention is needed most. Backed by testing across sports, the CLIMAWARM SYSTEM is engineered to tackle this problem head on, ensuring athletes can maintain optimal muscle temperature and maximise power output through the pre-race window.”, Margherita Raccuglia, Director of Athlete Performance at adidas.
