Get The CoolMax® Facts

We recently tested CoolMax® garments with competitive performance fabrics like treated polyester and polyester/cotton blends to see which fabrics performed the best.

In blind studies conducted in environmentally controlled conditions, we monitored athletes wearing our products and competitive products. We proved that CoolMax® fabrics keep athletes dryer and more comfortable.

And we proved--once again--that CoolMax® is the leading performance fabric. Read on for a brief summary of the tests. THE FACTS MAY SURPRISE YOU.

They'll definitely convince you of our superior performance benefits. And we're pretty sure they'll make the competition feel the heat. But we're cool with that.

TESTING PROTOCOL
Research was conducted at Eastern Carolina University in 1999 to substantiate the findings form a 1998 Brazilian study. Subjects were competitive athletes. Each athlete wore three shirts in a blind test--treated polyester, polyester/cotton blend, and CoolMax®. The athletes performed the same trial in each shirt with all other variables constant. They ran for 60 minutes in an environmentally controlled chamber with the temperature at 104 degrees F, humidity at 20%.

The CoolMax® Comfort System tetra-channel fibers pulling moisture away from your skin.

• Unique engineered fibers quickly move moisture to the outer surface of the fabric.
• Larger surface area of fibers allows for faster evaporation.
• More open fabric yarn structure provides outstanding breathability.
• Performance is built into the fiber--not an electrostatic of chemical fabric treatment that will wash out over time.
  

CoolMax® KEEPS YOU COOLER THAN
OTHER PERFORMANCE FABRICS.

CoolMax® is proven to help your body with thermo-regulation. Infrared images of the athletes' backs showed that the average skin temperature of athletes wearing CoolMax® was lower that when they wore competitive shirts. Reds and oranges indicate warmer skin temperatures.Greens, blues, and black indicate cooler skin temperatures.

CoolMax® KEEPS YOU BETTER HYDRATED.
Research shows that CoolMax® improves hydration status during exercise. This is because CoolMax® keeps you dryer and cooler that the competition, meaning that your body doesn't have to sweat as much in an effort to cool itself naturally.

Body weight was measured before and after exercise, and water intake was controlled. So changes in body weight pre- to post-exercise indicate water weight loss due to perspiration. Lower weight loss indicates less perspiration and better hydration.

Urine specific gravity shows how concentrated the urine is, which indicates how much water is available in the body. Lower urine specific gravity shows that there is more water available, indicating less perspiration and better hydration.







CoolMax® HELPS KEEP YOUR HEART RATE LOWER.
Because CoolMax® keeps you dryer, cooler and better hydrated, your body doesn't have to work as hard on thermoregulation, so your heart rate remains lower. This means that you have more energy for enhanced performance.

While specific results varied among athletes, overall results were consistent and proved that CoolMax® heart rates were lower overall.

PERCEIVED EXERTION
LEVELS ARE LOWER
WITH CoolMax®.

Using the internationally recognized Borg scale, test subjects rated their perception of effort and difficulty during exercise. Again, because CoolMax® is proven to help your body with thermoregulation, you have more energy, so your levels of perceived exertion will be lower.

CoolMax® IS MORE COMFORTABLE.
Athletes rated their comfort before and after exercise. 100% of the athletes stated that they were more comfortable in CoolMax® than in any other fabric tested.

IT'S A FACT.
Nothing performs better than DuPont Performance Fabrics. Our fabrics use superior technology. And our products have proven physiological benefits that are superior to the competition. If you'd like to beat the competition too, specify CoolMax® in your apparel and accessories.


Most of the data outlined here is from the most recent study performed at Eastern Carolina University. Other tests have been conducted at separate facilities with different test subjects. The findings in the other tests support the data included in this mailing.

The limited sample size from these independent research studies makes calculation of statistical significance at p<.05 difficult in many cases.
