Polartec has launched what it calls a “best-in-class fill insulation” called Polartec Power Fill that rounds out its range of temperature-regulating performance fabrics.
The Andover, Massachusetts-based provider of innovative textile solutions described Polartec Power Fill as a soft and pliable matrix of polyester engineered with a proprietary hollow fiber construction that is softer and more durable.
Power Fill is designed to form thousands of air pockets that continuously capture and contain body heat, while maintaining a resilient, equalized thermal layer between the colder air on the outside and the warmer temperatures on the inside.
A specially controlled melt process bonds the hollow fibers, increasing durability and drapability and eliminating the need for scrims or other stabilizers. This gives Power Fill unmatched warmth and design versatility for a wide range of styles and usage occasions, the company noted.
The polyester fiber’s inherent hydrophobic properties also work to ensure that Polartec Power Fill resists moisture absorption and dries quickly, while maintaining a high warmth to weight ratio.

Made with 80 percent post-consumer recycled content, Power Fill insulation technology provides greater warmth retention in colder conditions, without added weight or bulk.

Gary Smith, chief executive officer of Polartec, said, “Polartec created the category of active insulation with our industry leading range of Alpha temperature regulating product offerings and now Power Fill continues with innovative fill solutions for the coldest conditions.”
Polartec Power Fill is available in six weights and has been adopted first by San Francisco tactical clothing company Triple Aught for its Bastion Hoodie and M-65 liner jackets. For Fall 2018, Flylow, Millet and Giro will feature Polartec Power Fill.
Since its predecessor company Malden Mills invented modern synthetic fleece in 1981, the engineers at Polartec have continuously created innovative fabric technologies.
Polartec products range from lightweight wicking and cooling fabrics to insulation and weather protection textiles, and are utilized by leading consumer brands, the U.S. military and other global militaries, as well as the flame resistance, work wear and contract upholstery markets.
