The Cooling Game

Million Dollar Question: Which is more important to human performance, thermoregulation (regulating body temperature) or hydration?

Hint:  You can fall victim to heat stroke even when fully hydrated.

The correct answer is "Both", yet you're not alone in your surprise that thermoregulation is as critically important as hydration -- it's why sports drinks are on every athletic bench while cooling vests are virtually unknown by all but elite athletes. 

Think about wearing a cooling vest the same way you think about wearing your winter coat.

Without a winter coat, your body will attempt to warm itself by shivering. Shivering cannot keep you warm to the degree a warm winter coat can, but instintively we know this and bundle up appropriately. 

Without a cooling vest, your body seeks to cool itself by sweating. Sweating eventually results in dehydration, and is in no way sufficient in preventing heat stress and/or heat stroke.


PRECOOLING stalls the point at which overheating would normally occur. If your activity doesn't allow for cooling on-the-job, then this method of cooling is for you:

  • Precool for 30 minutes or longer to outlast your competition
  • Precool to boost your mental and physical endurance 
  • Precool while "warming up" to reserve your game-time performance


  • Throw on your cooling vest whenever you take a break to restore physical and mental endurance


  • Your body keeps sweating after extended activity in warm environments. Your cooling vest helps your body safely recover.
  • Ice Tubs are considered the gold standard for cooling an overheated athlete, but are not always available. The Maximo Cooling Vest is the next best option.
Important: Heat exhaustion can turn into heat stress within only a few minutes. If you, or someone in your presence, falls victim to heat stress or worse, call 911 for immediate medical attention. Cool first, transport second! Oro Sports + Safety cooling products are not a replacement for medical attention. With proper cooling practices, heat injuries can be minimized and/or prevented.

    Cooling Headbands

    Kewl Headband

    The cooling headband was a big hit with my daughter. She overheats so quickly, but this headband saved the day! A great fit and a long lasting cool.

    Kept me cool for 6 hours

    We own a small furniture store and this vest gave me a boost the way a cold glass of water gets you moving on a hot summer day. It was easy to use (threw it in the freezer whole) and I wore it over my undershirt and kept me from over heating. Love it!!!

    Your wonderful product is really helping me! "Pax"

    CoolPup Bands is helping me to stay cool in the heat of the day, and keeping me comfortable and less stressed due to my breathing complications from my neuromuscular disease that is causing me to struggle with Laryngeal Paralysis. My mommy Liz also is not stressing when I have to go out to potty! A very special thanks to Luanne for your compassion and help in choosing the CoolPup Bands for me...they really work!

    Super service, agreed to correct size of ice pack.

    Returning reply could be faster.

    A really quality product!

    I’m a 28 year old woman from Brisbane, Australia who suffers from Postural Orthostatic Tachycardia Syndrome (POTS) and practices ballet. The combination of Brisbane weather and serious heat intolerance means a hot day can be absolutely debilitating for me. I found the Oro sports vest because I was looking for something that wasn’t too bulky and would not embarrass me if I wore it in public or at ballet class. This product is really good, not only does it look great and is really well made structurally but the gel inserts keep me cool for hours, even without aircon.
    If I had to find fault with the vest it would be that it is designed as unisex and does not take a woman’s chest into account. On me it does not cool my entire front uniformly as my chest distorts the shape. But this is just nitpicking, the vest still works great. The only cool vests available in Australia are made for construction workers so I was really excited to see something designed specifically for sport (the freedom of movement is great!)
