ACTIVE WICKINGMove moisture away from skin.
Moves moisture away from skin to help reduce the damp feeling caused by perspiration during activity.
03
RAPID DRYINGFeel fresh again.
Helps release moisture from the fabric into the air quickly, supporting drying and comfortable wear.
BUILT IN.
STAYS COOL.
STAYS COOL.
Cooling built into the fiber.
Cooling technology is incorporated into the yarn and designed to remain through repeated washing. The foundation of cooling begins when the fiber is made.
02 / BORN IN THE USA
From Atlanta
to a world in motion.
brrr° is a cooling technology brand founded in the United States in 2014. It began with the idea of making the textiles we wear and touch every day cooler, drier and more comfortable.
Material development is based at its Atlanta, U.S. headquarters, with production operations in Taiwan and a global fabric partner network bringing the technology into products.
03 / MEASURED, NOT JUST FELT
Beyond the feeling.
Verified through testing.
Independent external laboratories evaluate
brrr° cooling, moisture transfer and drying performance separately.
Contact cooling
Qmax · W/cm²Measures how quickly heat transfers when fabric first touches the skin. A higher value indicates greater contact cooling.
