adidas' ClimaChill fabric technology is specifically engineered to keep you cool, regardless of the situation. Clothes constructed with this material are designed to feel cool on contact, maintain a comfortable microclimate, and provide enhanced breathability. This is done through the following:

• Cool on Contact: Aluminum Cooling Spheres are strategically placed in areas notorious for generating sweat. This helps to cool these warmer parts of the body, and results in an almost chilly feeling on contact.
• Climate Control: Specialized SubZero yarn, created from woven titanium fibers, draws heat away from your body, and is actually meant to maximize surface contact with your skin. As a result, additional heat is transferred away from your personal microclimate.
• Breathability: To optimize the functionality of the aforementioned features, ClimaChill fabric is constructed to feel lightweight and airy.
