brrr°® is a cooling performance fabric engineered to actively reduce skin temperature through a combination of cooling minerals, moisture-wicking fibers, and rapid drying technology. Built directly into the structure of the fabric, the cooling effect is permanent, delivering consistent comfort in warm conditions and during movement.
Why we use it
brrr°® is designed for days when heat, movement, and changing conditions all come into play. By combining three proven cooling technologies into one fabric, it delivers an immediate and continuous cooling effect that helps regulate body temperature, manage moisture, and keep you feeling dry. It’s performance-driven, but built for real life — from movement to everything after.
Instant Cooling
Cooling minerals embedded directly into the fabric create an immediate cool-to-the-touch sensation, helping reduce perceived skin temperature from the moment it’s worn.
Moisture-Wicking
Designed to actively pull sweat away from the skin and spread it across the fabric surface, helping maintain dryness and comfort during movement or rising temperatures.
Rapid Drying
Accelerates evaporation by distributing moisture across a larger surface area, allowing the fabric to dry quickly and prevent that damp, heavy feeling during or after activity.
Temperature Regulation
Three technologies work together to deliver a consistent cooling effect over time, helping regulate temperature throughout the day, not just on first wear.
How it works
brrr°® combines three cooling technologies into one fabric: cooling minerals, active moisture-wicking fibers, and rapid drying construction. Together, they create what’s known as the Triple Chill Effect — working to immediately and continuously reduce skin temperature while keeping you dry and comfortable.
When we use it
brrr°® is designed for warm weather, high sun, and active days when staying cool matters most. It performs best during movement, travel, or long days outside, when temperatures rise and you need a fabric that can regulate heat, manage moisture, and keep up without feeling heavy or restrictive.
FAQ

How is it different from regular performance fabric?
It combines three technologies — cooling, moisture-wicking, and rapid drying — into one system that works continuously.
Will the cooling effect wash out?
No, the cooling technology is built into the structure of the fabric and is designed to last over time.
Is it breathable?
Yes, it’s designed to allow airflow while pulling moisture away from the body.
