It’s hot. So hot that heat exhaustion or stroke are a real danger. Add some activity and you need some serious cooling.

The head is a great place to cool. That’s why you sweat so much there.

The High UV Buff® fabric was created to help. It uses your sweat to cool you.

A cooling fabric takes the moisture of the skin and spreads it super thin on the outer fabric surface. The heat evaporates the moisture creating a cooling effect

It is the highest cooling headwear fabric in the world. In fact it created the category Coolmax® Extreme in 2003.

The cooling feature of the High UV Buff® can help you in many ways:

  • Sweat in your eyes – A cooling bandana or sweatband
  • A cooling wristband
  • A neck cooler


You are a heavy sweater that hates the heat. You are in a tropical rainforest. Chances are that even the High UV Buff® fabric will fail you. At least you know that you’ve tried the best money can get you. Better get out of that place or take ice packs with you.

Also the fabric has to be flat on your skin. No air pockets allowed. Also not more than one layer.

I recommend to make the fabric moist and shake it before putting it on. This way you have an instant cooling effect on your skin. You don’t first have to sweat to get the cooling effect.

How to easily check other fabrics for MM

Test it

This one is easy. Best is to take your Buff® as reference. Do the following first with your Buff®. Then do it with any other fabric and you’ll be able to compare.

  1. Make the fabric wet and squeeze excess moisture out.
  2. Feel the fabric and memorise the temperature.
  3. Now shake the fabric vigorously in the air to activate any cooling process
  4. Now feel the fabric flat on your palm or on your cheek. Does it feel cooler or not.
