Coolcore Fibr-X

Coolcore (, the leader in chemical-free thermoregulating fabrics, introduces Fibr-X, an extruded single yarn which possesses the same thermal regulating performance as Coolcore’s original multi-fiber technology.

“The evolution of Coolcore’s single yarn innovation gives our manufacturing partners more flexibility than ever before to create innovative garments, accessories and fabrics with all the Coolcore technology benefits,” said David Ludd, Coolcore’s Vice President of Global Marketing.

Fibr-X features proprietary cross section designs that wick and transport moisture while promoting a superior evaporative process without chemical additives or treatments.

“While Fibr-X performs on par with Coolcore, as a single extruded fiber it reduces manufacturing time and materials,” states Dennis Ackroyd, Coolcore’s Chief Technology Officer/Founder.

Fibr-X yarn can be woven with other natural and synthetic fibers to create fabrics with additional performance characteristics or used alone to create high performance thermoregulating garments and accessories.

Fibr-X yarns are available now, with the first products featuring the yarn to be available in Fall/Holiday 2018.

Numerous leading outdoor, fitness, and running brands have selected Coolcore for their thermoregulating technology as have major retail brands including Cabela’s, L.L. Bean, Disney, Athleta, Klim and Dickies.

In 2013, Coolcore became the first US Company to receive the “Innovative Technology” award from the Hohenstein Institute, and remains the only company globally to receive it for “Cooling Power”.

Independently tested by the world-renowned Hohenstein Institute on its WATson test, which measures a fabric’s cooling and drying power, Coolcore’s fabric received the best scores against seven leading brands and three competing technologies.
