Exploring the Future of Cool at the Functional Fabric Fair in NYC

Performance fabrics are making major advances with better wicking technology, more stretch and greater breathability to keep us comfortable as we go about our everyday lives.

We think fabrics should also do more to keep us cooler.

That’s why brrr° developed a patented blend of natural cooling minerals that are embedded right into the polymer matrix of the yarn. The minerals work together with active wicking and rapid drying technologies to create a “Triple Chill Effect.

brrr°’s cooling sensation is immediate and continuous, and unlike other fabrics that are sprayed or coated to create a cooling effect, brrr° technology is a permanent the yarn so it won’t ever fade or disappear with repeated washings.

Product development executives, textile scientists and retail buyers explored the wide variety of brrr° cooling fabrics that were showcased at the Functional Fabric Fairby Performance Days trade show in New York City on July 22 and 23.

brrr°’s library includes hundreds of woven and knit fabrics, and the technology can be integrated into virtually any existing fabric used by manufacturers and retailers.

The cooling, wicking and drying capabilities of brrr° consistently outperform other brands on the market, and each fabric is rigorously tested by globally recognized independent labs to prove its effectiveness. You can see test results here.


“Consumers expect more from their clothes and the fabrics they touch throughout the day,” said Julie Brown, Vice President of Sales at brrr°. “Drawing heat and moisture away from the skin will keep people cooler and more comfortable so they can feel their best.”


brrr° cooling fabric technology is already being used or will be featured in upcoming product launches by Southern Tide, GAP,Jos. A. Bank, Men’s Wearhouse, Mizzen+Main,Coral Coast Clothing, Greyson, GILLZ, The Gameheadwear and CAT apparelto name a few.

Superior Cooling Capabilities of brrr° Fabrics Confirmed

Article by: Innovation in Textiles

New test data by independent global labs proves that brrr° cooling technology consistently outperforms other products available to consumers and can keep you cooler and more comfortable in everyday activities.

brrr°’s patented cooling technology combines natural minerals, active wicking and rapid drying to create a Triple Chill Effect that instantly and continuously draws heat and moisture away from the body, the company explains.

brrr° nylon and polyester fabrics outperformed numerous other comparable products in independent laboratory tests that measure Qmax (cool to the touch), wicking and dry time. For example, brrr° nylon has a Qmax score of 0.217, which is more than twice as cool as the 0.103 score of a competing brand. brrr° polyester dried 34% faster than another brand.

“These independent tests once again confirm brrr°’s superior capabilities in removing heat and moisture so people can feel comfortable and confident in whatever they do,” said Apurba Banerjee, Chief Scientist at brrr°, who oversaw the testing.

The testing was conducted in the first half of 2019 by Intertek Testing Services Taiwan in accordance with standards set forth by two globally recognized groups: the American Association of Textile Chemists and Colorists (AATCC) and the Committee for Conformity Assessment of Accreditation and Certification of Functional and Technical Textiles (FTTS).

brrr° spends a significant portion of its operating budget to validate and authenticate the cooling, wicking and drying properties of its fabrics. Because brrr°’s cooling technology is embedded in the structure of the yarn of the fabric, it won’t ever diminish over time with repeated washings, according to the manufacturer. Major retailers including Gillz, Southern Tide, CAT apparel, Bigfoot Sock, Mizzen+Main, Jos. A. Bank and Men’s Wearhouse use brrr° cooling performance technology.

Say Goodbye to Hot, Sweaty Denim With brrr° Cooling Technology

When Levi Strauss and Jacob Davis patented their riveted denim work pants a century and a half ago, comfort wasn't exactly top of mind for the rugged garments that were designed for durability in harsh manual labor conditions such as mining.

Denim’s tightly packed yarns and rough fibers trapped heat and sweat, but that didn't matter very much as long as the metal rivets prevented the seams and stress points from tearing.

Fast forward 150 years and consumers can’t get enough denim — demand for skinny jeans, denim skirts, denim jackets and dozens of other products continues to grow faster than many other categories.

Denim has also become more common in the workplace. Coca-Cola’s James Quincey famously wore jeans to the office on his first day as CEO to send a subtle message to employees that it was a new era for the world’s largest soft drink company.

But it's time for denim to get an upgrade.

brrr° developed patented methods for integrating natural cooling minerals into a nylon and polyester sheath core that's surrounded by a layer of naturally-derived regenerated cellulosic fibers. It feels like cotton and creates a cooling sensation along with active wicking and rapid drying, while a touch of spandex provides stretch and comfort.

brrr° Chief Scientist Apurba Banerjee wrote about cooling denim innovation in this article published by the American Association of Textile Chemists and Colorists

She also discussed some important parameters that must be followed during manufacturing and production in order to optimize the cooling effects of brrr° technology. (Spoiler alert: hydrophobic silicone softeners inhibit wicking)

The results from independent lab tests are clear: brrr° denim feels 38% cooler to the touch than comparable traditional denim, it dries up to 47% faster and wicks 2.5 times better.

Forbes Feature: "Startup brrr° Keeps Clothes Cool With Textile Tech"

Startup brrr° is headquartered in Atlanta, Georgia.
Cool is a science. And this is about textile technology, not fashion.

Although clothes made from brrr° yarn may look good, the cool factor is in the company's Triple Chill Effect, according to a company rep.

The newest news from the Atlanta, Georgia, startup is test data from an independent lab that shows brrr°'s technology can keep people cooler and more comfortable in everyday activities. As The Fonz would say, "Aaaay!"

For readers who don't get the reference, suffice it to say that brrr° uses a patented technology that combines natural minerals, active wicking, and rapid drying, according to the company, that instantly and continuously draws heat and moisture away from your body.


The tests, by Intertek Testing Services in Taiwan, showed that brrr°'s nylon and polyester fabrics consistently outperformed a number of comparable products in lab tests that measure something called Qmax (cool to the touch), wicking and dry time.

A summary of the testing results.

This must be some magical coating that wears away in time though, right?

Brrr° says its technology is embedded in the structure of the yarn of the fabric, so it won't diminish over time with repeated washings.

What's the green factor, other than climate change?

A company rep says: "We can use recycled polyester (mostly from beverage bottles) or recycled nylon (mostly from fishing nets, industrial waste, fabric scraps, etc.) and integrate our patented cooling fabric technology into those recycled materials that get turned into yarn."

If you've never heard of brrr°, you may still be familiar with clothing that uses it, which is sold by retailers including Gillz, Southern Tide, CAT apparel, Bigfoot Sock Co., Mizzen+Main, Jos. A. Bank and Men’s Wearhouse. Brrr° is an "ingredient brand" that licenses its tech to retailers so they can integrate it into their manufacturing process, and cut and sew the clothes and other items themselves.

"Our mill partners have the factories/equipment to break down the recycled product into pellets, and then we blend and extrude those pellets with brrr° cooling minerals to create the yarn that gets made into fabric," the rep adds. "Many retailers have been asking for recycled content in performance fabric in recent months, so this is a relatively new offering for us and we expect it will grow quickly as we bring it to market."

The company has been around since 2014 and is led by Founder and CEO Mary-Cathryn Kolb, who previously held senior positions at Spanx, Seven Jeans, TOMS Shoes and Von Dutch.

Why ‘Cool to the Touch’ Matters at Point of Sale

When we began brrr° with a vision of creating cooling fabrics, we knew it would be important for consumers to be able to quickly and noticeably tell that our products are truly different.

brrr° fabrics feel cool to the touch, thanks to a patented blend of natural cooling that are embedded right into the yarn of the fabric so it’s permanent and won’t ever fade.cooling fabric

It’s a big differentiator at the point of sale, where people can touch clothing and other products made with brrr° and feel a noticeable difference in how that fabric feels compared with another similar item made with traditional fabric.

This cooling effect is measured with a Qmax test (FTTS-FA-019) that was developed in accordance to international standards by the Committee for Conformity Assessment of Accreditation and Certification of Functional and Technical Textiles (FTTS).

In recent tests by an independent laboratory called Intertek Testing Services Taiwan Ltd., brrr° nylon had a Qmax score of 0.217, which is more than twice as cool as the 0.103 score of a competing brand.

brrr° polyester scored 0.144, which was at least 14% better than the next-closest competitor and a whopping 35% better than the lowest-performing competitor.

Beyond feeling cool when you touch it, brrr° combines the power of natural cooling minerals with active wicking and rapid drying to create a “Triple Chill Effect” that instantly and permanently draws heat and moisture away from your skin. brrr° helps you stay cooler, drier, more comfortable and more confident so you can do your best work and be your best self.

We’re so confident in brrr°’s superior cooling powers and our extensive testing with independent labs to validate results that we put it in our tagline: Proven to keep you cooler.

brrr° Chief Scientist Banerjee Gives Glimpse Into the Future of Cool

How much can our clothes really do to improve our bodies regulate temperature and get rid of excess heat? Quite a lot, actually.

New technologies such as cooling mineral blends, active wicking, and rapid drying can be used together to create powerful cooling effects that draw heat and moisture away from our skin to keep us cool and fresh.

brrr° Chief Scientist Apurba Banerjee shared insights into the future of these and other technologies at the REThink materials conference hosted by ITA Americans last week and emphasized the importance of testing products to prove effectiveness before making cooling claims.

Some fascinating things that scientists are exploring next include trying to replicate the biological functions of Saharan silver ants, which have tiny hairs that reflect sunlight and keep them cool, and other sustainable products like recycled polymers that have cooling properties, Banerjee said.

brrr°’s Banerjee Speaks at ITA’s ReThink Conference

brrr scientistbrrr° Chief Scientist Apurba Banerjee will make a presentation about modern functional fabrics at the Innovate Textile & Apparel ReThink Conference this week in Raleigh, North Carolina.

Banerjee’s talk is titled “What is Cool? Here’s What You Need to Know About Today’s Functional Textiles.”

In it, she will talk about how “cooling” technology hasn’t changed much in two decades as many companies still rely on just wicking, and how that stagnation mentality is coming to an end as innovators including brrr° make deep investments in R&D.

Although the industry has made big advances in understanding the science behind performance textiles, there is still a cloud of misinformation and unproven claims that confuse manufacturers and consumers alike.

Banerjee breaks down the science behind human thermoregulation, busts common myths about cooling textiles and offers a better definition for cooling performance.

She also talks about advances in cooling technologies, bolstered by competitive analysis of current cooling products and offers a peek into new technologies that are revolutionizing the future of cool
