About the ICED Cap

The ICED Cap is a billed cap made of mesh fabric that is designed to cool down athletes (runners, triathletes, tennis players, golfers, etc.) or people at beaches, swimming pools, etc. in hot weather. Its unique feature- the top of the Cap- is a roomy pocket for ice with a drawstring closure.

ICED Caps have been used by testers while-

  • Competing in Ironman, Half-Ironman, and Olympic and Sprint Triathlons
  • Running races of varying distances
    • 5K
    • 10K
    • Half-marathons
    • Marathons (including the Boston Marathon)
    • Ultramarathons (50K and 100K)
  • Training outdoors
  • Lounging at the beach, swimming pools, etc.

In very hot running races or triathlons, our tests have shown that running paces can be reduced by as much as 30 seconds per mile with the use of an ICED Cap.  During training tests, the runner’s heart rate is significantly reduced when running at the same pace, or, if the heart rate is kept the same in training runs in the same temperature conditions, the runner will maintain a higher pace.

For example, on two different 85°F days, a test runner ran 8 miles on the same course keeping his heart rate at 140 bpm in both runs.  The run with the ICED Cap with ice was completed at about 30 seconds per mile faster than the run without ice.  Our tests have shown that running with ice in an ICED Cap lowers the effective temperature about 20°F as far as running paces are concerned.   This means that if a race temperature is 80°F, your body will feel like it is about 60°F.  The creator of the ICED Cap uses his own Cap in all races of about 70°F or higher.
