Imagining the Future of Cool


Textile innovator brrr° became a leader in cooling yarns and fabrics several years ago when the company introduced new technology that combines the power of natural cooling minerals, active wicking and rapid drying.

brrr° creates a “Triple Chill Effect” by instantly and continuously drawing heat and moisture away from the skin to keep you cooler and more comfortable all day long — whether you’re at the office, working from home, exercising, playing sports, or enjoying some leisure time with friends.

What sets brrr° apart is that its cooling technology is permanently embedded in the structure of the yarn itself. Unlike other brands that use sprays and coatings to achieve a cooling sensation, brrr° technology won’t ever fade or wash out over time.

Anchored in advanced scientific research and development, brrr° rigorously tests each fabric through globally recognized third party labs to verify its cooling properties and prove that its technology outperforms other brands.

Major retailers including Simms FishingForlohGreyson ClothiersLandseerSouthern TideVineyard VinesADAYKit + AceShinestyPajamagramSheex and many others use brrr° cooling technology to make their apparel even better.

Building on its foundational cooling technology, and now offers a performance fabric called brrr° Pro that has a more intense cooling effect.

brrr° Pro harnesses the power of micro cooling technology to create the coolest polyester in the market, with enhanced cooling fibers that intensify the concentration of brrr° cooling minerals. brrr° Pro also amplifies moisture management for hyper wicking, while performance drying delivers a fresh and crisp experience.

Scientists at brrr° spent more than three years developing brrr° Pro, and they tested dozens of formulas before landing on their most advanced technology yet. Because it helps keep people cooler, drier, and more comfortable so they can perform their best at work and at play, brrr° Pro can also help reduce reliance on air conditioning and other energy sources — which is good for the planet.

The Atlanta-based company is also committed to sustainability, and offers numerous eco-friendly fabrics such as brrr° Recycled Poly and other blends of natural and synthetic yarns. While brrr° has enjoyed Global Recycled Standard (GRS) certification through its mill partners for many years, the company recently received direct GRS certification to assure customers that its products are being made in a sustainable way.

brrr° scientists continue to develop new advanced cooling products, with numerous research projects actively underway.

The company is also constantly innovating new woven and knit fabrics with interesting tactile and visual textures such as creative patterns and physical textures like jacquard.

brrr° offers a library of hundreds of fabrics to choose from, for ultimate flexibility and adaptability for a wide range of applications and uses: business attire, casual apparel, athletic apparel, athleisure, pajamas and intimates, bedding, furniture textiles and many other industries.

About brrr°

brrr°® was founded in 2014 with a vision to develop advanced cooling fabric technology that could improve the items we wear and touch in our everyday lives. brrr° uses natural cooling minerals, active wicking and rapid drying to create a Triple Chill Effect™ that instantly and continuously draws heat and moisture away from the skin. Its newest offering, brrr° Pro, uses the power of micro minerals to deliver performance level cooling for athletic and activewear apparel. The Atlanta-based company is privately held and led by Founder & CEO Mary-Cathryn Kolb, who previously held senior positions at Spanx, Seven7 Jeans, TOMS Shoes and Von Dutch.

Why Global Recycled Standard (GRS) Certification Matters

Where is your recycled yarn coming from, and what material is going into it?

Businesses that manufacture recycled yarns are validated by the Global Recycled Standard (GRS) certification to show customers and consumers that they are committed to internationally recognized standards and practices for sustainability.

GRS certification was created to reduce the impact on people and the environment from the production of materials by driving a higher percentage of recycled content in products. 

The GRS certification also provides assurance for retailers and consumers that products are being made in a more sustainable way. The standard is managed with input from key stakeholders such as recyclers, suppliers, brands, and retailers all over the world.

GRS verifies that recycled materials are used, and it also tracks responsible production methods. Companies must demonstrate a chain of custody, and obtain certification from a professional third party that audits and validates each step of the supply chain.

Products that have earned a GRS certification can include the GRS logo on their products to let consumers know the items have been sustainably produced. 

brrr° has enjoyed GRS certification for many years through our mill partners, and now we also have a direct GRS certification for both brrr° recycled nylon and brrr° recycled polyester yarns.

brrr° is committed to reducing our environmental footprint as we develop and produce advanced cooling fabric technology in more sustainable ways so we can divert materials from landfills and make a minimal impact on local and global ecosystems.

brrr° offers several recycled cooling yarn options in both recycled nylon and recycled polyester, as well as recycled nylon/polyester blends. brrrº cooling technology includes natural cooling minerals, active wicking, and rapid drying to provide instant and continuous cooling to keep any lifestyle comfortable.

GRS certification is important to us, and it’s one of many ways we show our customers that we’re a responsible citizen and committed to protecting our planet. Learn more about brrr° recycled cooling yarns.

brrr° Founder & CEO Mary-Cathryn Kolb Presents at Venture Atlanta 2021

We were excited to see brrr° Founder & CEO Mary-Cathryn Kolb take the stage at the #VA2021 investor conference hosted by Venture Atlanta.

This was a record-breaking and hyper competitive year for the conference with more than 400 applicants, and brrr° was honored to be chosen as one of the most promising tech companies in the Southeast.

It was the second time Kolb was chosen to present on-stage in front of a limited group of investors and sponsors including Invesco, Mailchimp, Stax, Cherry Bekaert, Truist and Goldman Sachs to name a few.

“The energy and pent-up demand to connect growth stage companies with investors who are actively seeking to place funds was palpable at Venture Atlanta,” said Kolb, who founded brrr° in 2014 after previous leadership roles at companies including Spanx and TOMS Shoes. “We deeply appreciate the opportunity to tell our story of innovation and traction at a time when we are actively raising a new round of venture capital.”

The Future of Cool: brrr° Pro

We’re relentless when it comes to developing new advances in cooling fabric technology, especially against the backdrop of rising global temperatures. 

That’s why we spent more than three years and experimented on dozens of formulas before we landed on our most sophisticated performance cooling fabric yet: brrr° Pro.

brrr° Pro uses enhanced cooling fibers, hyper wicking, and performance drying to elevate the Triple Chill Effect® that instantly and continuously draws heat and moisture away from the skin.

It’s a new concentrated cooling technology that harnesses the power of micro-cooling technology and advanced dispersion techniques to intensify the cooling power of brrr°. 

Like all brrr° products, brrr° Pro is independently lab tested by globally recognized third-party labs and proven to outperform other brands.

Because it can help keep people cooler, drier, and more confident so they can perform their best at work and at play, brrr° Pro can also help reduce our reliance on central air conditioning and that’s good for the planet.

Can Our Clothes Keep Us Cooler?

Global temperatures continue to trend hotter, and many people feel like there isn’t much they can do about it as individuals.

What if we could choose clothes and other household items that reduce our need for central air conditioning and energy consumption?

brrr° advanced cooling fabric technology can draw heat and moisture away from our skin, which keeps us cooler and more comfortable even when the thermometer rises.

Better thermoregulation and less sweat means we’re less likely to crank the thermostat down to colder temperatures, and that lowers our use of fossil fuels that contribute to global warming.


brrr°’s patented technology uses natural cooling minerals, active wicking, and rapid drying to create a Triple Chill Effect®️ that instantly lowers the temperature of our skin and encourages the evaporation of moisture. brrr° fabrics are independently lab tested and proven to perform better than other brands. To learn more, check out our test results here.

Man, It’s Getting Hot Outside

Our planet has gotten a lot warmer over the last several decades, and the pace of change is accelerating rapidly. 

As scientists study the causes and politicians negotiate policy changes, there’s one thing consumers can do to contribute to a healthier planet: look for advances in fabric and other materials that help keep us cooler and reduce our dependence on fossil fuels.

To lower your energy consumption for central air conditioning, the U.S. Department of Energy recommends turning your thermostat up several degrees in the summer while you’re away and then lowering it to a more comfortable temperature when you return. 

Doing this, and taking the reverse approach during the cold winter months, can help reduce your energy bill by as much as 10% per year.

Fabrics that draw heat and moisture away from your skin can help you feel cooler and drier all day long so you won’t need to turn the thermostat as low when summertime temperatures rise.

brrr°’s patented cooling fabric technology combines the powers of natural cooling minerals, active wicking and rapid drying to create a Triple Chill Effect®️ that instantly and continuously draws heat and moisture away from the skin. Each brrr° fabric is independently lab tested and proven to keep you cooler and outperform other brands.

Clothing, undergarments, bedding, accessories, and numerous other products are powered by brrr° fabrics. Learn more here.
