Extreme Heat. The High UV Buff® fabric cools you. So good you can use it as a face mask whilst running.

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.

Heat and motorcycle gear don’t go well together. The cooling fabric around the neck can ease the heat (Motomonkey)

Motorcycle gear in the heat is dreadful.

But there is a gap between the helmet and the jacket. Your neck. Your neck is a great place to get cooling.

The High UV Buff® as helmet liner does a few good things. It

  • Cools the neck in the heat
  • Draws the sweat out of the helmet. Keeps the helmet dryer
  • Keeps the bugs out of your jacket

Hot, humid? No wind somewhere in the jungle? The cooling High UV fabric will give you heat relief.

A lot of great places to visit are in hot & humid climate zones.

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.

Only Non-Toxic and Non-Itchy Ingredients – Oekotex Certified

The most dangerous way for a toxin to enter the body is not through the digestive system, but through the skin

A Buff® passes the most stringent test for fabrics. Free of anything irritating or harmful for babies.

Did you know that fabric ingredients are grouped into toxic or safe and non-itchy?

The difference in costs is huge.

This article shows you how to spot the safe products and why Buff® headwear ticks the right boxes

What makes you itch?

There are 2 main reasons for fabrics itching.

The first is bacteria. Call it bad hygiene or simply fabrics that make you sweat and breed bacteria (cheap polyester beanie hat for example).

The second is toxic and irritating ingredients in making the fabric.

There are ingredients available that can not only make you itch but also severely impact your health.
These ingredients are on a list and banned in most 1st world countries.

How safe are we in Australia?

Not at all, unfortunately.

Australia has no tests or regulations regarding safe textile ingredients. You can import into Australia whatever you like.

This leads to Australia being the only 1st world country supplied with 3rd world quality clothing.
Whenever we mentioned in China that we are from Australia and want headwear that passes the Oekotex test, we heard something like, “Why do you want to waste money on Oekotex. You are from Australia. You do not need this …”.
We were quite shocked at first but got used to hearing it all the time.

Here is a nice article from Choice that goes into more detail
My favourite quote is

Products that are made in China for the Australian market could not even be sent back to China, as many of them would not meet the Chinese product safety standards but are acceptable here.

How do you find safe and non-itchy clothing in Australia?

You look for the Oekotex® certificate.

Oekotex® is a worldwide testing standard for classifying the safety of clothing.

Just look out for something like the logo below. If you spend more money to make your product safe, you will have it tested. If you can’t find it, assume the worst.
Especially if it’s our beloved “The same, just cheaper…” products.

You can always go to the AITEX website and enter the test number. That will give you all the details of the test.

So what are Buff® tested to?

The more intensive the skin contact of a product and the more sensitive the skin, the stricter the human-ecological requirements that need to be complied with.

All adult products are rated to class 2. This is the class for adults close to the skin clothing (underwear, socks, headwear,…)

All baby products are rated to class 1. The most stringent class.

UV/Sun Protection

Ouch. That must hurt. Skin cancer aware? The BUFF® fabrics protect. (Jonny Butler / Pat Ford)

Sunburns hurt. Skin cancer can kill.

The Original EcoStretch and the Coolnet UV fabric give you UPF50 excellent protection (98% UV/Sun protection).

Scan of a UPF report issued by ARPANSA
Skin Cancer aware? If it’s not rated it will not protect you.

This is an example of a UPF report. It was performed by the founders of the UPF rating ARPANSA. Nowadays both, Original EcoStretch and CoolnetUV, fabrics are constantly monitored for their UPF rating at the factory. The testing company is Aitext Textile Research Insitute.

BUFF® Original EcoStretch and CoolnetUV multifunctional headwear come with a label that clearly states the standard (AS/NZS 4399:1996), the UPF Rating and the testing laboratory.

Beware of UPF Claims without reference to the test!

We see a lot of tubular headwear that advertises sun protection claims but has no labels and no mentioning of the test standard. Those claims are bogus. Why?

A thin fabric without UPF rating cannot protect you from skin cancer.

For example, a T-shirt is only around UPF 6. That’s because it just filters out enough UVB to stop a sunburn. It will not stop you from getting skin cancer because it doesn’t filter out UVA enough.

UVA is harder to filter and it goes deep into your skin so the damage is not visible.

That’s where special dyes and other ingredients enter the game that absorb both UVA and UVB satisfactory. This function can only be tested and proven in a laboratory.

That’s why sun protective clothing is more expensive than non-protective clothing.

So if you see a tube with a UV protection claim and it doesn’t clearly state the UPF rating with the testing standard and the testing laboratory do yourself a favour and walk away.

Endurance Sports

Sunscreen sweating out and no time to replace. The BUFF® CoolnetUV protects. The fabric cools enough to wear in a desert.

Running events in the sun are a prime example. You’re sweating throughout the day and no sunscreen would work for long. You also don’t have any time to constantly apply sunscreen.

Events like the Marathon des Sables have their custom made BUFF® CoolnetUV for their participants. It’s not perfect but it’s better than burning to crisps.


They are thin fabrics so stretching them too much or wearing them thin over several years reduces the protection.
